Effect of heat treatment on the microstructure and properties of 2024 aluminum alloy

2024 aluminum alloy

Aluminum and aluminum alloy is the largest amount of non-ferrous metals, the highest yield of material, is a pillar industry of the national economy, widely used in aviation, transportation, building materials, machinery, packaging and other industries, is also an important defense material. 2024 co-metal Al-Cu-Mg-based high-tough aluminum alloy, due to the high strength, heat resistance, excellent formability and resistance to damage and other characteristics, has become the main structural materials for the aerospace industry it has. Therefore, exploring new heat treatment process system, improve the overall performance 2024 aluminum alloy has great practical significance.

Solution treatment incubation times are 50min, the solution temperature was 460,480,500 and 520 ℃, the use of the installed furnace temperature, after the solution is complete, remove the cooling fast. Research on the impact on performance solution time is about 500 ℃ sample into a heat treatment furnace insulation 30,50,70 respectively and 90min, after the solution is complete, remove the cooling fast. When the impact of aging on the performance of research, the first sample was 500 ℃ × 50min the solution treatment, then the sample at different temperatures for a long time of aging heat treatment, and every once in a while to test the mechanical properties of a sample. Aging temperatures were 130,170,180,190 and 210 ℃. Using the installed furnace temperature, cooling method for quick cooling. Quickly removed after every 1h, rapid cooling hardness test, then quickly back into the heat treatment furnace continued aging heat treatment, a total aging time of 15h.

Heat treatment process has on the microstructure and properties of 2024 aluminum alloy is a significant impact, the higher the solution temperature, the alloying elements, the greater the concentration of the solid solution, a solution to improve the degree of concentration after quenching supersaturated solid solution of the higher, Aging will have a higher strength; with the holding time, the alloy hardness first increased and then becomes more gentle, and decreased. Hardness aging temperature increases, the arrival time of the peak aging required shorter, the faster aging, 180 ℃ aging reached the highest peak value and timeliness arrived; at 500 ℃ solid solution heat 50min, peak hardness values ​​appear highest.

Aluminum Container Manufacturing Process

One of the most used packaging materials is aluminum. Think about the products that you use every day. The hair spray which you used this morning was packaged as an aluminum aerosol bottle. The energy drink that you had right after breakfast was packaged in an aluminum beverage bottle. And the air freshener that you sprayed throughout the house came in an aluminum aerosol bottle as well. Surely aluminum packaging is used in dozens of industries, ranging from personal care and cosmetics to food and beverages to household products to pharmaceuticals. Still, given its widespread use, surprisingly few people know how that aluminum bottle ends up in their hand. This article will provide an overview of the impact-extrusion process-the most common process used in the manufacturing of aluminum containers.

The impact extrusion process is used by aluminum bottle manufacturers worldwide. It requires a hydraulic press which houses a ‘punch’ and a metal slug which is cooled and lubricated before the process begins. The metal slug is placed on a die, below the punch, and the punch then makes contact with the slug, deforming it and shaping it around the punch. The slug is shaped by a single impact, and is then removed from the work piece by a ‘counter punch’ mechanism.

This process can be used not only for aluminum but a host of softer metals; these include brass, tin, mild steel, magnesium, and titanium. It is used widely because of the abundance of advantages that it provides. When used for aluminum, the impact extrusion process has advantages which are both economic and technical. An aluminum bottle made using this method can be made quickly, last longer, have a lower weight, and have a superior surface quality.

The typically cited drawback is that the impact-extruded aluminum bottle is slightly less environmentally friendly than an aluminum bottle made by another process-the Coil to Can process. The Coil to Can process (C2C) uses thirty to forty percent less aluminum than an impact-extruded bottle. This is because impact extrusion requires that the bottle uses about 3 times more aluminum than the traditional aluminum can for insulation purposes. At the same time, however, any aluminum product is relatively environmentally friendly, because aluminum bottles and cans are easily recycled. The use of recycled aluminum requires only 5% of the energy that is needed to manufacture a product using new (non-recycled) aluminum.

Obviously aluminum plays a huge role in the packaging industry. And the metal is particularly important as a cheap, comfortable, and sustainable material. As a result, the role that the impact extrusion process plays in the manufacturing of aluminum bottles, aluminum aerosols, and other specialty aluminum packaging is extremely important. Without impact-extruding there would be none of the custom aluminum packaging designs and shapes that are seen in innovative beverage bottles everywhere. It is beneficial to executives in industries that use aluminum bottles to know the manufacturing process. Doing so will help them make better decisions as to their packaging needs, and help with the branding and marketing that is so important.

The Benefits Of Aluminum Windows And Doors

Aluminum Windows And Doors

There are a variety of favorable benefits that aluminum windows and doors can supply a homeowner with. In fact, Aluminum is one of the most cost effective materials that a homeowner can invest in for their windows. If you’re on a budget then you can enhance traditional aluminum for reinforcement, but still save money.

So, for the most part a homeowner can have attractive windows and doors created from aluminum at a most exceptional value. Again, more composite materials can be added to improve the quality. Even if you use only a small portion of aluminum in the composite materials you’ll find some savings stemming from this. These are extremely reliable in many elements. Furthermore, aluminum can come in traditional features.

There is standard aluminum, which is used to construct windows and doors for those who live in the more mild regions. Then there is the thermal proof style of aluminum doors and windows. This latter style is for those who live in the regions of the United States, which face the harshest of elements, specifically the winter and summer months. Thermal proofing guarantees that high quality energy efficiency that homeowners are seeking today.

Creating A Customized Look For Homeowners Today

Many homeowners consider high-level aluminum windows and doors for sections of their homes such as a newly constructed patio. Aluminum patio doors come in a variety of styling choices that can match a home perfectly, as do the windows. If it hasn’t been mentioned aluminum windows and doors are customized and can have several finishes to satisfy a homeowner.

This is an individual preference and varies by tastes. However, aluminum windows and doors that are reinforced, or double insulated provide high security, along with that perfect energy efficiency. Many manufacturers often prefer aluminum windows themselves. They are some of the most easily customized.

They are also easily upgraded to strengthen and support a home’s exterior. One main feature that most homeowners aren’t aware of is the fact that many aluminum windows and doors come with lifetime guarantees. You won’t lose money by investing in these at all. Just a few of the reasons that aluminum windows themselves are beneficial is strictly due to the fact that these:
– Offer far more color options than any other vinyl window possibly can
– They can be customized to suit the homeowners preferred tastes
– They also have the ability to strengthen windows that are larger and in combination with others
– They can strengthen the external frame structures

Quality That Is Affordable And Provides Lasting Benefits

When it comes to aluminum doors, some of the same benefits are found. You might not think a door could be customized if aluminum, but it certainly can. Aluminum doors outlast even those traditional wooden doors. They also provide more dexterity and versatility than any patio vinyl door could hope for.

Aluminum doors and windows have a protective resistance against corrosion. It’s true that while many doors and windows will eventually corrode, and need replaced, aluminum can be far more dependable in some cases. Shockingly, aluminum windows can hold up under brute force longer than vinyl windows and wooden windows.

Even wooden windows sometimes depend on some form of aluminum reinforcement. While wood and vinyl windows used to have higher energy resilience, aluminum windows are just as reliable when they have a thermally insulated glazing system. This has become quite common today.

Aluminum is Economically Preferred by Most Manufacturers for Windows and Doors

Aluminum is simply a preferred composite material for many reasons. Aluminum can be recycled, and it offers durability that is hard to find. Aluminum holds up under extreme wear and tear too, providing perfect economic savings. Furthermore, it is the preferred material for school windows.

The reasoning behind this is simple. The windows are much larger for one thing. Secondly, aluminum simply can’t rust and it won’t create any condensation issues either. These features actually minimize maintenance that has to be carried out.
The same can be said for aluminum windows and doors in general. Both are time efficient when it comes to cleaning and maintaining them.

Furthermore, aluminum can be enhanced in any number of ways. They can be painted practically any color, or they can be used as enhancements for wood windows with regard to weather proofing and such.

The techniques for aluminum windows and doors are just really limitless from many respects. Both aluminum windows and doors are almost resistant to chipping, cracking, and even denting it would seem. Even if there is a hairline scratch, it can be easily corrected on this material. Vinyl is not so easy, and wooden windows definitely aren’t easy to correct.

Design Mistakes in Aluminum

Aluminum Alloys

Background
As a rule, designers of metallic structures have learned to design using steel. When designing with aluminum, however, the engineer must not base the design on prior experiences with steel or any other material. The alloy selection, proper joint design and the choice of an optimal welding process may all be a function of the base material. While aluminum obviously obeys the same laws of mechanics as all other materials, it must be approached differently than steel when welded. Aluminum structures are not necessarily more difficult to design or weld than steel structures, they are just different.


Don’t Just Choose the Strongest Alloy

Aluminum is often chosen as a structural material for applications in which weight savings are important. Very often, the designer will choose the very strongest alloy available. This is a poor design practice for several reasons. First, the critical design limitation for many structures often is deflection, not strength. In such cases, the modulus of elasticity, not the tensile properties, will govern the design. The modulus of most aluminum alloys, weak and strong alike, is approximately the same (one-third the modulus of elasticity of steel), so no benefit accrues from using the strongest alloy. Second, and most importantly, many of the strongest aluminum alloys are not weldable using conventional techniques.

When we speak about aluminum alloys being “weldable” or “non-weldable,” we are usually referring to the alloy’s ability to be welded without hot cracking. Alloys that are extremely susceptible to hot cracking are not considered appropriate for structural (load-carrying) applications, and are generally put in the non-weldable category. Hot cracking in aluminum alloys is primarily due to the chemistry of the alloy and the weld bead. For virtually every alloying addition, the cracking sensitivity varies as alloy content increases as shown in Figure 1. Weldable alloys have a composition that falls either well above or well below the maximum cracking sensitivity. In some cases, such as that of 6061, which is very crack-sensitive if welded without filler material, the weld cracking sensitivity can be reduced to acceptable levels with the addition of a high silicon or high magnesium filler metal. The additional silicon or magnesium pushes the solidifying weld metal below the cracking sensitivity level. In other alloys, such as 7075, it is not possible to design a weld filler alloy that results in a crack-resistant chemistry. These are considered to be non-weldable.

Alloys are broken into two groups: heat-treatable alloys and non-heat-treatable alloys. A relative assessment of weldability is also given for each of these.

The non-heat-treatable alloys are composed of the 1XXX, 3XXX, 4XXX, and 5XXX series. It is not possible to strengthen these alloys by heat treatment. They can only be strengthened by cold working (also called strain hardening). The 1XXX alloys, such as 1100, 1188, or 1350, are essentially pure aluminum (99+% purity). They are relatively soft and weak, with good corrosion resistance, and are usually used where high electrical conductivity is required, such as for bus bars or as electrical conductors. They are also used in certain applications that require a high degree of resistance to corrosion. All of these alloys are readily weldable.

The 3XXX series of alloys have various levels of manganese (Mn) added to strengthen them and improve their response to cold work. They are of moderate strength, have good corrosion resistance, and are readily weldable. They are used for air conditioning and refrigeration systems, non-structural building trim, and other applications.

The 4XXX series of alloys have silicon (Si) added as an alloying element to reduce the melting point and increase their fluidity in the molten state. These alloys are used for welding and brazing filler materials and for sand and die castings. They are the least crack-sensitive of all the aluminum alloys.

The 5XXX series of alloys have magnesium (Mg) added in order to increase their strength and ability to work-harden. They are generally very corrosion resistant and have the highest strengths of any of the non-heat-treatable alloys. Increasing magnesium content in these alloys results in increasing strength levels. These alloys are commonly available in the form of sheet, plate and strip, and are the most common structural aluminum alloys. They are generally not available as extruded sections, because they are expensive to extrude. They are readily weldable, in most cases, with or without filler metal. However, there is an Al-Mg cracking peak at approximately 2.5% Mg, so care must be used in welding alloys such as 5052. It should not be welded autogenously (i.e., without adding filler metal). Weld filler metal with a high Mg content, such as 5356, should be used to reduce the crack sensitivity.

The heat-treatable alloys are contained in the 2XXX, 6XXX, and 7XXX alloy families. The 2XXX family of alloys are high strength Al-Cu alloys used mainly for aerospace applications. In some environments, they can exhibit poor corrosion resistance. In general, most alloys in this series are considered non-weldable. A prime example of a non-weldable alloy in this series, which is attractive to designers because of its high strength, is alloy 2024. This alloy is commonly used in airframes, where it is almost always riveted. It is extremely crack-sensitive and almost impossible to weld successfully using standard techniques.

Only two common structural alloys in the 2XXX series are weldable: 2219 and 2519. Alloy 2219 is very easily weldable and has been extensively welded in fabricating the external tanks for the U.S. space shuttle. This alloy gets its good weldability because of its higher copper content, approximately 6%. A closely related alloy, which is also very weldable, is 2519. It was developed for fabrication of armored vehicles. Although there are detailed exceptions to this rule, the designer should probably consider all other alloys in the 2XXX series to be non-weldable.

The 6XXX series of alloys are the alloys probably most often encountered in structural work. They are relatively strong (although not as strong as the 2XXX or 7XXX series) and have good corrosion resistance. They are most often supplied as extrusions. In fact, if the designer specifies an extrusion, it will almost certainly be supplied as a 6XXX alloy. 6XXX alloys may also be supplied as sheet, plate and bar, and are the most common heat treatable structural alloys. Although all alloys in this series tend to be crack-sensitive, they are all considered weldable and are, in fact, welded every day. However, the correct weld filler metal must be used to eliminate cracking. Additionally, these alloys will usually crack if they are welded either without, or with insufficient, filler metal additions.

The 7XXX alloys are the ones that usually trip designers up. They are the very high strength Al-Zn or Al-Zn-Mg-Cu alloys that are often used in aerospace fabrication, and are supplied in the form of sheet, plate, forgings, and bar, as well as extrusions. With the few exceptions noted below, the designer should assume that the 7XXX alloys are non-weldable. The most common of these alloys is 7075, which should never be welded for structural applications. In addition, these alloys often suffer from poor corrosion performance in many environments.

A few of the 7XXX series defy the general rule and are weldable. These are alloys 7003 and 7005, which are often seen as extrusions, and 7039, which is most often seen as sheet or plate. Some common uses of these alloys today are bicycle frames and baseball bats, both of which are welded. These alloys are easily welded and can sometimes offer strength advantages in the as-welded condition over the 6XXX and 5XXX alloys.

There is one other exception to the general rule that 2XXX and 7XXX alloys are unweldable. There are a number of thick cast and/or wrought plate alloys designed as mold plate material for the injection molding industry. These alloys, which include Alca Plus, Alca Max, and QC-7, are all very close in chemistry to 7075 or 2618. The designer should absolutely avoid structural welds on these alloys. However, welding is often performed on these alloys to correct machining mistakes, die erosion, etc. This is acceptable because there are only low stresses on such welds and, in fact, the weld is often in compression.

This discussion has tried to make a few points:

First, when designing a structure of any kind, don’t scroll through the nearest list of aluminum alloys and pick the strongest
Realize that some alloys, often the stronger ones, are non-weldable. Make sure the selected alloy is readily weldable
    Recognize that some alloys or alloy families are more suitable for some applications than others

One more caveat: when welding aluminum, the designer must not assume that the properties of the starting material and the properties of the weld are equivalent.
Why Isn’t the Weld as Strong as the Original Base Metal?
A designer of steel structures generally assumes that a weld is as strong as the parent material, and the welding engineer who is responsible for fabricating the structure expects to make a weld which is as strong as the steel being used. It would be tempting to assume that the situation is the same when designing and fabricating aluminum structures, but it isn’t. In most cases, a weld in an aluminum alloy is weaker, often to a significant degree, than the alloy being welded.
Non-Heat-Treatable Alloys
Alloys in this category (i.e., 1XXX, 3XXX, 4XXX, and 5XXX families) are produced by a cold working process: rolling, drawing, etc. After the cold working process, the alloy is given the designation of an F temper (as-fabricated). Alloys are then often given a subsequent annealing heat treatment, after which they are classified as an O temper (annealed). Many alloys are sold in this condition. Thus the correct designation for a plate of 5083 which was annealed after rolling is 5083 – O. One of the attractive properties of these alloys is that they can be significantly increased in strength if they are cold worked after annealing. Figure 2 shows what happens to several alloys with varying amounts of cold work. For example, alloy 5086 rises in yield strength from approximately 18 ksi (125 MPa) to 40 ksi (275 MPa) and is now said to be strain-hardened. A complete designation for this alloy would be 5056-H36. The H temper designation can be somewhat complicated, since it is used to designate a number of processing variables. However, the last digit designates the level of cold working in the alloy, with 9 denoting the highest.

A common mistake in designing welded structures using non-heat-treatable alloys is to look down a list of properties, disregard the O temper material, and choose an alloy of the highest temper because it is significantly stronger. This would seem to make sense, but it often doesn’t, because the heat of welding acts as a local annealing operation, significantly weakening the heat affected zone (HAZ) of the weld. If one plots the yield or tensile stress versus distance from the weld, a curve such as that seen in Figure 3 is obtained. If the design is based on the strain hardened properties, the allowable design stress will usually be above the actual yield point of the HAZ. Although it may seem counter-intuitive, the fact is this: No matter what temper one starts with, the properties in the HAZ will be those of the O temper annealed material due to the welding operation. Therefore, the design must be based on the annealed properties, not on the strain-hardened properties. Because of this, it usually doesn’t make sense to buy the more expensive strain hardened tempers for welded fabrications. One should design with and specify the alloy in the O temper and up-gauge as necessary.

An obvious question is whether anything can be done to restore material properties after welding a strain-hardened material. Unfortunately, the answer is almost always no. The only way to harden these materials is through mechanical deformation, and this is almost never practical for welded structures.

Heat-Treatable Alloys
The situation is somewhat different when welding the heat-treatable alloys. Alloys are heat-treated by initially heating the material to approximately 1000°F (540°C), holding the temperature for a short time, and then quenching it in water. This operation is intended to dissolve all the alloying additions in solution and hold them there at room temperature. Alloys in this condition are said to be in the T4 temper and have significantly higher strengths than the same alloy in the O temper. Depending on the alloy, “natural aging” at room temperature can lead to further strength increases over time. This takes place over a matter of days or, at most, a few weeks. After that, the properties will remain stable over decades. If one buys T4 material, it is stable and the properties will not change over the course of a lifetime.

However, most alloys are given an additional heat treatment to obtain the highest mechanical properties. This heat treatment consists of holding the material at approximately 400°F (205°C) for a few hours. During this time, the alloying additions that were dissolved in the prior heat treatment precipitate in a controlled manner, which strengthens the alloy. Material in this condition is designated as T6 (artificially aged) temper, the most common heat-treated alloy temper.

Again, the complete temper designation system is actually much more complex than this, but understanding the T4 and T6 tempers will help to overcome some of the most common mistakes made when designing aluminum weldments. It is important to note that heat treatable alloys can also be strain-hardened after heat treatment, and this can further complicate the temper designation.

Remember that the aging treatment is performed at approximately 400°F (205°C). Any arc welding process gets the HAZ much hotter than this. Therefore, welding constitutes an additional heat treatment for the HAZ. Some alloys experience an additional solution heat treatment, while other alloys become overaged in the HAZ. This results in degradation of material properties, especially if the as-welded properties are compared to T6 properties. For example, the minimum specified tensile strength in ASTM B209 for 6061 – T6 is 40 ksi (275 MPa). Most fabrication codes require a minimum as-welded tensile strength of 24 ksi (165 MPa), which is a significant degradation.

As when designing for the non-heat-treatable alloys, the designer must not use the parent material properties in design. Realistic as-welded properties must be used. It is difficult to generalize what these properties are. They change from alloy to alloy and depend strongly on the starting temper of the alloy. Most design codes contain as-welded properties for aluminum alloys and these should be used.

With heat-treatable alloys, however, there are some ways to recover some of the material properties of the parent. Figure 4 shows a plot of tensile stress versus distance from the weld for 6061, revealing curves for both T4 and T6 material in both the as-welded (AW) and post-weld-aged (PWA) conditions. The PWA condition represents a weld that is subsequently aged for one hour at approximately 400°F (205°C). Post weld aging improves the mechanical properties for both T4 and T6 starting materials. In fact, often times it is better to weld in the T4 condition and post weld age after the welding process.

There is one final alternative to discuss. If after welding, the structure is given a complete heat treatment (i.e., solution treat at 1000°F [540°C], quench, age at 400°F [205°C]), all of the material properties (even in the weld) will be recovered and T6 properties will be obtained. This practice is frequently followed on small structures such as bicycle frames, but it is impractical for larger structures. Furthermore, the quenching usually causes enough distortion of the structure that a straightening operation is necessary before aging.


Conclusions

In the design of welded aluminum structures, too often the differences between steel and aluminum are not taken into account. To recap, common mistakes include:

Not all aluminum alloys are weldable. In general, the least weldable alloys are also the strongest alloys
The weld will rarely be as strong as the parent material
The HAZ will have O temper annealed properties for non-heat-treatable alloys regardless of the initial material temper
    For the heat treatable alloys, the as-welded properties will be significantly lower than the properties of the T6 alloy temper
    Post-weld heat treatment can help to restore the mechanical properties of welds in heat treatable alloys

 

The application of aluminum in thermoforming tool

THERMOFORM TOOLING

 

When it comes to the use of aluminum thermoforming, it refers to a process by which tools are produced from a flat sheet of aluminum under both certain temperatures and pressures. While many elect to use wood, paper, glass, or plastic for this purpose, aluminum serves as the go-to option for lasting design and functionality purposes. Thermoform tooling, when combined with advanced finishing techniques, is thought to produce results not all that different from what would be expected of injection molding. No matter the medium used, thermoform tooling is particularly effective because of its ability to offer close tolerances, tight specifications, and sharp detail.

Aluminum thermoforming is a particularly desirable option as opposed to injection molding as well because of the relative ease of using it to produce any number of parts of a particular size and shape. In addition, unlike injection molding, aluminum thermoforming allows designers to test for design flaws and to better understand customer acceptance of the design prior to mass production of it.

Much of the thermoforms ability to replace more expensive and time-consuming injection molds for design purposes can be attributed to its vacuum fixture, which is necessary when a part needs trimming. Vacuum fixtures not only serve the purpose of helping make a reverse impression of the part  but aid with the mounting of this impression into the vacuum box. This is important because the trim fixture is responsible for holding the part being trimmed under vacuum pressure as a way of ensuring consistent results.

This is particularly important given the various uses of thermoformed products in the construction of large panels, housings, and enclosures, many of which require further refining their design for optimal performance. For example, aluminum thermoforming allows for design for one-sided parts more easily than does injection molding. Whereas, moveable features requiring trimming, fabrication, or assembly might be suited for other modeling techniques or approaches. In this case, thermoforming only works on controlled sides because of this technique’s strict adherence to close tolerances. This means that the side away from the mold cannot be controlled despite being able to successfully predict what will happen on the uncontrolled side.

MOLD FORMATION SPECIFICATIONS

According to a United States-based thermoform mold manufacturer, Associated Thermoform Inc., when working with aluminum or any other material to create a mold, the desired thickness of that medium is .040” to .500”.  Using mediums of this thickness most allow the manufacturer to capture both sharp and crisp details with close tolerances including undercuts, formed-in textures, formed-in logos, formed-in hardware, as well as custom coloring. What’s more, if the design calls for a multi-dimensional design, then two individual sheets are joined together to form a twin sheet form to capture double-walled parts, similar to what would be produced if a roto-mold were made, featuring both better cosmetics and more details.

TYPES OF ALUMINUM THERMOFORMING MOLDS

There are several different kinds of thermoforming molds; Machined, Cast Aluminum, and Composite Molds. Each of these different type molds serves a different purpose, whether one’s looking for a textured or multi-dimensional design, whether one is looking to have a prototype created for future refining or if the design is more set in stone and one’s looking for a mole that can go the distance. Each of the molds varies in its effectiveness of use depending on their intended purpose as follows:

  • Machined Aluminum Molds

This type mold is most typically constructed for shallow parts with small draw ratios. Aluminum is most often used in constructing these type molds because of their ability to hold cost to tolerances. When being constructed, the molds they are mounted on a control base as a way of controlling the mold temperature as the mold is formed. A number of different mold types can be machined using aluminum molds including male and female molds and vacuum- and pressure-form molds. The preferred medium for these type molds is aluminum specifically because of its ability to offer texturing as well as features including both loose and pneumatic cores and inserts.

  • Cast Aluminum Molds

These type molds are generally cast using a composite material at a foundry using a pre-designed pattern. Generally built for parts, these molds feature large draw ratios. Much like Machined Aluminum Molds, Cast Aluminum Molds, can take the form of male or female molds and be vacuum- or pressure-formed. At the foundry, temperature controls are cast into both the back and sides of the molds. This allows the molds to be easily adapted for the purposes of adding texture, loose or pneumatic cores, or inserts.

  • Composite Molds

These type molds are most appropriate for either prototyping or smaller scale productions. In constructing these molds, cost-effective composite materials are utilized to build the mold. Parts produced by Composite Molds are more basic in design than those produced by either the Machined or Cast Aluminum Molds. This means that they are particularly effective in evaluating fit, form, and function in deciding whether design changes are necessary. Unlike the aforementioned molds, although these molds are vacuum forming, they are not temperature controlled and have a limited lifespan.

Whichever type mold is selected, aluminum thermoform molding is a durable choice as opposed to wood, paper, glass, or plastic construction molds. Aluminum molds are effective in making sure molds are close to tolerances, tight specifications, and sharp details. Aluminum thermoforming is a particularly desirable option as opposed to injection molding as well because of the relative ease of using it to produce any number of parts of a particular size and shape.

They also serve as a particularly flexible choice when trying to create a number of prototypes, each with their own degrees of functionality because of the variability of design offered by this type medium mold. This makes aluminum a particularly desirable option when deciding between more solid and temporary construction choices. And, aside from being most cost efficient than injection molding just in terms of sheer design, aluminum thermoforming allows designers to test for design flaws and to better understand customer acceptance of the design prior to mass production of it, which also saves money.

Categories and Detailed description of Aluminum furniture

Aluminum furniture

Aluminum belong to the category of non-ferrous metals, due to the wider application, described separately as follows: aluminum and die-cast aluminum alloy commonly have two kinds. Which consists of up to 92% purity aluminum as the main raw material, while adding increased strength, hardness, wear resistance and other properties of the metal elements, such as carbon, magnesium, silicon, sulfur, etc., composed of various ingredients “alloys.”

1 Aluminum
Aluminum common such as screens, aluminum windows and so on. It is the use of extrusion process, namely aluminum and other raw materials in a furnace after melting, extruding it through a die out of shape, it can be extruded various profiles of different sections. The main properties, namely strength, hardness, wear resistance according to national standard GB6063. Advantages are: light weight of only 2.8, no rust, design changes quickly, mold into low, longitudinal elongation up to 10 meters. Aluminum appearance bright, matte points, its treatment process using anodized oxide film surface treatment to achieve 0.12m / m thickness. Beijing plans produced in accordance with product introduction aluminum wall thickness is selected to optimize the design, not the market, the thicker the better, you should see a cross-sectional structural requirements for the design, it can be uneven at 0.5 ~ 5mm. The thicker the more hard-line laymen think, is wrong view.

Aluminum surface quality also difficult to overcome shortcomings: warping, distortion, black line, punch and white lines. High level design by designer and mold and production process is reasonable, it can avoid these defects less noticeable. Check defect inspection methods should state that the line of sight 40 ~ 50CM to distinguish defects.

Aluminum use in a wide range of furniture: wall skeleton, various suspension beams, tables, table legs, trim, handles, trunking and cover, chair pipes, etc., can be ever-changing design and use!

Although the advantages of aluminum and more, but there is not the ideal place:
Without aluminum oxidation treatment is easy to “rust” causing performance degradation, inferior longitudinal strength iron products. Surface oxide layer plating scratches easily compare the wear resistance. High cost, relatively high cost iron products out of about 3 to 4 times.

2 die-casting aluminum
Die-casting alloys and profile processing methods were compared using equipment they are different, it’s the raw material in aluminum (about 92% purity) and alloy materials, the melting furnace into the die casting machine molding. Company renderings die-cast aluminum imaging product shape can be designed as toys, shapes, convenient connections in all directions, in addition, the strength of its high hardness, and can be mixed with zinc to zinc-aluminum alloy.

Die-cast aluminum molding points:
1, die-casting
2, rough polishing to mold than expected
3, fine polishing

On the other hand, the production of aluminum die-casting process, should die in order to create, its cost is very expensive molds are higher than other mold injection molds. At the same time, mold maintenance is very difficult to design a material error is difficult to reduce repair.

Die-cast aluminum Disadvantages:
Each time the number of production and processing should be more than just low cost. Polishing products more complex production cycle costs than slow injection of about 3 to 4 times higher. Requirements should be bigger screw holes (diameter 4.5mm) to connect power only stable Adaptation: table legs, Pantai fittings, decorative head, aluminum seal pieces, table and coffee table backwater like, a very wide range.

Aluminum products have a very powerful effect everywhere

aluminum products

 

Aluminum elements, though not needed by the body metal element, but in life made by aluminum elements aluminum products everywhere, is one of the important and rich crustal abundance of metal elements. So aluminum products What are the advantages? And in what situations can play a role? Why do not we also look through the importance of aluminum products processing aluminum products in life.

One of the most common aluminum cans workpiece is not only light weight, large volume, easy to transport trafficking; and the appearance of colorful, very popular with young people affected. Cigarettes and some candy packaging also contains aluminum element in fact, not only can make the packaging looks upscale, competition, also have some protection. Because for this type of food, the fear of the weather or other factors cause the internal reasons damp, a damp but food packaging, it can easily lead to food spoilage mold. And aluminum products processing packaging has good oxygen barrier effect of the barrier can be certain limits of water molecules in the air, the food kept in a dry environment.

Aluminum products processing furniture advertising industry still plays an important influence, for example, glass door frame will choose aluminum products, not only lightweight and easy to pull, but also conducive to daily cleaning. Some of the advertising industry billboard frame is aluminum-based products, in addition to the quality of light in the mobile hanging outside long life is one of the main reasons. Because the billboards are generally placed outdoors, if the other common metal such as iron or copper, the former is easily oxidized to rust, which is likely to be theft criminals, resulting in losses. And aluminum products have a certain resistance to corrosion, outdoor wind and rain is not easily damaged, it can remain fresh brightness appearance.

Aluminium also has good plasticity and extensibility, conductive aluminum products, although not as copper, but the effect of ventilation aluminum products processing to produce aluminum wire and cable than copper or Mom is not, and aluminum products have a certain insulation , the use of safer, in the wire and cable industry is also a popular choice.

Although there is no common aluminum, gold, silver, copper and other precious metal, but aluminum products processing was in everyday life and production in the consumption greatly, it is a essential metal products. However, some aluminum products are not environmentally friendly, can be used in the loss of aluminum products should be sent to specialized recycling facility, can not be thrown away, the destruction of the environment.

you can’t live without aluminum alloys

Aluminum alloys is really no stranger for everyone. Basic necessities of life, almost everything is inseparable from aluminum.

Such as eating, aluminum pots, aluminum bowls, aluminum chopsticks.For use, aluminum mirror, aluminum rivets clothes, cell phones, computers,cars, trains, aircraft. About living, houses, aluminum alloy doors and windows, aluminum ceiling, aluminum wardrobe, aluminum tables.

It can clearly be seen we can’t live without aluminum alloys.

Today mainly introduces the indoor use of aluminum alloys.

aluminum alloys

The biggest advantage of an aluminum alloy that greatly improve the mechanical strength and surface hardness of aluminum, and still maintain the inherent characteristics of lightweight aluminum, its value is greatly increased. Especially aluminum surface treatment after diversification, both with shiny metallic luster, smooth surface and is very fine, soft color gorgeous, a high performance, versatile interior decoration materials.

Aluminum alloy is widely used in interior decoration, except for doors and windows, ceiling, walls, handles, but also in the form of composite materials for aluminum composite panel and aluminum tubes.

Aluminum decorative panels are made of pressed aluminum sheet with a ceiling material for the ceiling, the interior decoration is widely used. It summarizes the main advantages are:

(1) light weight, ceiling weighs only about 3kg.

(2) It is convenient to install, construction speed, completion can be used. This is because the aluminum trim board ceiling installation is finished, no further for other decoration.

(3) aluminum trim board ceiling is pure metal material, not only has the texture of the metal, and particularly dry, pretty, bold lines, crisp style, gives a sense of elegance.

(4) In addition to the ceiling joists bearing rod members, but also the role of both fixtures, compact structure, beautiful appearance.

Take advantage of aluminum alloys, Let our lives better.

Do you often ignore it—-Garbage can?

It can be said that Garbage can is a symbol of urban progress, Garbage cans are more common in big cities than small cities and rural areas. It can helps us purify the city and keep the streets clean. It may be lots of garbage all over the streets without them.

Most of Garbage cans are made of aluminum. Aluminum Garbage cans are strong and durable, not expensive, easy to clean.

Metal trash can have a more durable nature in use, aluminum Garbage can, can be used to recycle more, high practical value, is now using more devices cities.

Outdoor trash used for more to adapt to changes in the environment; we are in life, is to see a lot of outdoor trash, have experienced a lot of wind and rain, it is still able to withstand more natural washing use with more convenience factor.

Trash implementation, we are one in environmental protection is well represented, more often, will always raise a lot of awareness of energy saving in life, but also to protect our health.

 

Are you a fan of MUJI? Have you ever used an aluminum pen?

As you know, Muji’s products are very delicate and special all over the world. Are you a fan of MUJI? Have you ever used an aluminum pen?

Aluminum pen is not common on the market, but more and more manufacturers use aluminum material to produce pen, and MUJI have one which is really awesome.

Pure aluminum is a soft metal, poor compressive strength, highly ductile, since hard enough, so in writing the daily exposure to the environment, easily bump damage, so aluminum pen parts are not the kind of daily use often friction parts, aluminum alloy after adding certain ingredients that can produce a variety of aluminum alloy, can maintain its original features lightweight, but also increase the hardness and toughness. Aluminum pen body, lightweight and easy to carry.

There are a variety of pen material. Human extensive use of metal materials of various containers, including pen manufacturing, people have been found in Pompeii bronze pen, artists with handmade pen, materials including precious metals, of course, customized products to meet the different needs of the wealth class.

With the technology and the development of smelting technology projects, including copper, silver and gold and other metals can be stamped and tube bending, which can be used to manufacture metal cap and pen body. In many cases the grassroots metal such as copper, will be covered with a thin layer of gold or silver and other precious metals, at first this process is mechanical rolling, then gradually being replaced by more efficient plating process. In many cases, the stainless steel cap and pen body in terms of durability and economy by consumers on all fans. A second chance, palladium and titanium metals are also used as material pen, and achieved success in the late 1970s, through difficult experiments, pen manufacturers through modern technology has produced several lightweight titanium pen.

Do you love to drink Coca Cola? Aluminum Cans?

At present,about 1.7 billion people around the world consumers are drinking Coca-Cola products every day, sold about 19,400 bottles drink per  second. So you must drink it. But do you know its packaging?Aluminum Cans,Glass Bottles, Plastic Bottles?

I think Aluminum Cans are the best pack,do you know why? Let me explain slowly.

1.Since the appearance of the aluminum in the air will form an oxide film, namely aluminum oxide Al2O3, which makes aluminum even at high temperatures over 100 degrees will not be oxidized, aluminum cans also have this appearance of an oxide film, even inside containing a liquid (liquid solution of aluminum and oxygen can accelerate the formation of the oxidation reaction), it will not be easy to rust.

2.The relative density of aluminum is smaller than the same volume of aluminum iron to small, hands cans, of course, the more light the better, who want to hold a few hundred grams when shopping ?

3.The aluminum industry has been relatively mature, high-speed mass production by aluminum, and aluminum plasticity, and through various other metals to facilitate the transformation into alloys, aluminum hardness, plasticity and even memory (that is, after deformation recoverability) has greatly improved, it can be said to be extremely versatile inexpensive metal.

4.Aluminum recycling is very convenient, the use of aluminum is also very good, resource utilization can be developed to 120%, the big reason is the use of aluminum regeneration.

Some beer packaging also use aluminum cans.

Detect-Metals stocks and processes kinds of  aluminum product: aluminum sheet metal,aluminum plate,aluminum pipe,aluminum foil and so on.

You certainly do not know there is such material on the LED tube

It is an energy-efficient era,I believe that every family are using LED tubes.But if you know one of the materials to make LED lamps is aluminum.

aluminum tube

Different from the traditional lighting LED lamps, generally have a very obvious sign:heat sink . Not because the LED temperature is high need for cooling. On the contrary, it is because LED is a cold light source, the chip was “afraid of the heat,” only to do the heat, so he can work safely.

LED lamp kit material mainly in the following three kinds: aluminum tube; glass tube; plastic tube. The best heat dissipation of them is aluminum tube.

Now many manufacturers of high-power LED heat sink cooling housing application basic using different aluminum alloy material, its thermal conductivity varies, cooling rate of some materials can not meet the LED operating conditions. It can not be ignored aluminum plate and thermal silica, thermal grease material aspects, the actual life quality of materials used, will directly affect the work of LED cooling conditions.

 

Do you care the case when you buy a laptop?

when you buy a laptop, you need to consider something: case, CPU, video card, memory, hard drive, price, etc. What is the case refers to? Maybe we think of color, process design, but we really need to know is the material, which is very important to effect the weight, heat, strong security, etc.

In fact, nothing more than common notebook shell material so few: carbon fiber, polycarbonate PC (PC-GF – ##), ABS plastic, aluminum-magnesium alloy and titanium alloy . Here, we will focus on aluminum-magnesium alloy and titanium alloy.

1.Aluminum-magnesium alloy

DELL aluminum alloy case

 

Typical: DELL

The main elements are generally aluminum, and then mixed with a small amount of magnesium or other metal materials to enhance its hardness. By itself is metal, its thermal conductivity and strength is particularly prominent.

In general, the hardness is ABS plastic enclosure several times, but weighs only one-third of the latter is often used in high-end ultra-thin notebooks or smaller sized housing.

Aluminum-magnesium alloy casing silver make the product more luxurious, elegant, and easy to color, surface treatment can be personalized into powder blue and the pink for laptops considerably, which is plastic and carbon fiber unmatched. Thus become the preferred aluminum-magnesium alloy casing material portable notebooks, currently most manufacturers of notebook computers are used magnesium alloy shell technology. Not very sturdy aluminum-magnesium alloy wear-resistant, high cost, relatively expensive and difficult than ABS molding (required stamping or die-casting process), so the laptop is generally only used on the aluminum-magnesium alloy cover, rarely organic type with aluminum-magnesium alloy to produce the entire cabinet.

Advantages: high strength, light weight, good heat dissipation.

Disadvantages: high cost, paint easy to wear.

2.Titanium Alloy

Thinkpad titanium alloy case

 

Typical: THINKPAD

Titanium material can be said to be an enhanced version of the aluminum-magnesium alloy, its main ingredient is aluminum. Titanium and aluminum-magnesium alloy in addition to the incorporation of different metal itself, the biggest difference in the sense that also permeate the carbon fiber material, regardless of the heat, strength or surface texture are superior to aluminum-magnesium alloy, and better processing performance, appearance ratio aluminum-magnesium alloy more complicated.

Titanium is a key breakthrough toughness stronger, and become thinner. On strength and toughness, the alloy is three to four times magnesium alloy. The higher strength and toughness, can withstand greater pressure. As for thinness, titanium thickness of only 0.5mm, is half the magnesium alloy, the thickness halved allows laptops smaller and more petite thin.

The only drawback is the need by welding titanium complex processing procedure, in order to make the complex structure of the laptop case, these production processes derived considerable cost, so very expensive.

Advantages: Set all of the above material on the merits.

Disadvantages: complex machining programs make expensive.

 

 

 

 

Do you like flying? Do you really acquaint the aircraft?

aircraft aluminum

Since the beginning of 1903,  the Wright brothers complete his famous first flight, aircraft of modern civilization becoming indispensable means of transport. It is a profound change and affect people’s lives, opening people to conquer the sky of history. Airlines spend millions of dollars per year inspecting their aircraft and making sure they are safe. Aircraft is the most efficient transportation so far, do you like flying? Do you really acquaint the aircraft?

The materials used are mainly the aircraft aluminum, followed by steel, composites and titanium alloys. And now the proportion of composite materials and titanium alloys is increasing. B777, the total weight of the composite material 11%, 7% titanium, aluminum 70%, steel 11%. While only 1% B747 composites, titanium 4%, aluminum 81%, steel 13%. Why  to choose aircraft aluminum? Aircraft aluminum is lighter materials can reduce the weight of flight, toughness is relatively good, the wings meet the quiver.

Compared aircraft aluminum to ordinary aluminum , the strength, hardness, toughness, fatigue resistance and plasticity of aircraft aluminum have higher requirements. There are a variety of aircraft aluminum:

1, duralumin: aluminum-magnesium-copper alloy. The aviation industry’s most widely used aluminum alloys. Common grade 2024,2A12,2017A, strength, toughness, good fatigue resistance, good plasticity. Used to make skin, bulkheads, wing ribs and the like.

2, super-hard aluminum: magnesium aluminum-zinc-copper alloy. Common grade 7075,7A09, high yield strength and ultimate strength to withstand load, used to make wing airfoil skin, beams and so on.

 

 

Farglory Dome—-Impressive Building built with titanium

Farglory Dome

Farglory Dome

Titanium in aerospace engineering in many appear now to be able to accommodate tens of thousands of people far Yuta Pengrowth Saddledome, its public safety factor will be more demanding, especially in the far north city center Yuta Dome is not only Taiwan a new landmark, better enhance the international visibility, more people will be proud of the building, by the public’s attention, much Yuta Arena in understanding titanium having energy security and many other advantages, the actively contributed titanium applied Farglory Dome building, decided to roof and curtain wall developed by using cold-rolled titanium sheet, showing kindness to support the large-scale construction of public works, and broke the past by foreign manufacturers imported titanium sheet market.

Farglory Dome can best demonstrate large curtain wall and part of the roof of the building aesthetic appearance, after a complete assessment, based on the following reasons, the selection of titanium sheet:

 

1, considered far Yuta Dome need to use 50 years, titanium sheet due to corrosion excellent to prevent corrosion due to acid rain caused by the perforation, can significantly enhance the construction was life;

2, using a titanium sheet was built to improve the fire safety of the melting point of titanium is 1660 ℃, can avoid the spark Derivatives of the fire problem.2009 Beijing CCTV that is due to the use of only 420 ℃ melting point of titanium zinc plate as the curtain, and the fireworks took place Shi melt titanium zinc plate wear caused by the fire, the entire building burned;

3, high strength titanium, the low density, structural load is light, can enhance the effect of anti-Taiwan earthquake building;

4, low thermal conductivity of titanium, can effectively cut off from the outside heat, using titanium roof can significantly reduce air conditioning consumption, save money on electricity, it is in response to the most carbon reduction good choice;

5, titanium glamorous appearance and color, may exhibit the characteristics of a vibrant, application examples around the world have hundreds of buildings, such as the Guggenheim Museum, New Zealand, the National Science Centre, and the mainland of the Beijing National Grand Theatre.

The Farglory Dome (http://www.farglorydome.com.tw/)will use cold-rolled titanium sheet, breaking the monopoly of foreign manufacturers in the past by the market. In the domestic construction steel titanium far Yuta Dome, but also allows the world with admiration, the future of Taiwan have the opportunity to copy the big Dome internationally.

Application of titanium sheet and titanium alloys in the ship

 

20150813022916649

From the actual findings speculated that the ship’s legal life of Ti than steel, aluminum is much the captain, the actual life will be longer.

Titanium ship advantages:

1. Hull light. The density of titanium is 4.5g / cm3, smaller than Fe7.9g / cm3. But with Ti have the same size 2.5mm enough boat, hull made of titanium quality is FRP30%, 10% lighter than aluminum. Since titanium does not need to spray anti-rust paint surface ship, it also eliminates the need for quality coatings.

2. The speed increase. Since the boat light. The same shape of the ship, the ship’s engine than titanium alloy and aluminum alloy boat engines smaller 15%. If you use the same engine, the speed can be increased by 15%. In addition, the ship and the water surface without direct contact with the coating, also reduces the coefficient of friction with the water, thereby increasing the speed of the boat.

3. fuel costs and reduce the amount of CO2 generated. Titanium boats and high speed light weight make the unit mass, a significant decline in unit fuel costs sail away. This is not just sail reduce funding. The prevention has become an international problem of global warming is very effective.

4.The corrosion resistance. Pt in seawater as titanium sheet as corrosion. So we do not need spraying anticorrosive coating. FRP though not rust. Difficult to remove. Corrosive aluminum boat, but also easily attached to marine life, it is difficult to remove. Therefore, FRP boats and Al alloy boat hull and bottom must be coated to prevent corrosion and paint adhesion of marine organisms.

5. Hulk recycling. FRP ship waste difficult to recycle. Waste can be recycled, environmentally friendly.

6. excellent stability. Titanium boat even in bad weather rarely appear vertical and horizontal shake.

7. noise, vibration small. Titanium boat bottom is 2.5mm titanium sheet . Very thin, do not worry about the vibration.

 

 

iPhone6 and iPhone6 + why so easy to be breaking bend

iPhone6 and iPhone6 + why so easy to be breaking bend?

QQ截图20150910114126

Whether the phone is easy to bend, there are two key factors, one is material, and the other is shape.

The first is the material, based on everyday experience, we should be able to feel, stainless steel commonly used in mobile phones, liquid metal (zirconium alloy) aluminum, magnesium alloy, plastic, stainless steel is the stiffness (resistance to deformation) and elastic best overall performance ; the zirconium alloys and magnesium alloys are rigid, poor flexibility; rigid plastic is poor but good elasticity; rigid aluminum is poor, poor flexibility.

Followed by the shape, we can imagine the phone into a surface of a rectangular box is empty. So everyday experience, if the side walls of the box is very low, so it can only rely on the strength of the basic bottom plate, while if the side wall is high, you obviously relatively soft material is difficult breaking move. Principle would not have to explain, everyone will know the feel of it is correct. Reinforced sidewalls, be sure to have a great contribution to the overall strength, of course, you go to increase the thickness of the bottom is also possible.

iPhone5 and 5S, replaced the aluminum material, this would lead to a sharp decline in overall strength, because aluminum is quite soft, and too prone to plastic deformation, so large that force is applied up, directly bent.

BUT IPhone 6S uses a new generation of aviation aluminum,and will never afraid of being bent breaking.

Apple found to iPhone6s and iPhone6s Plus a new rear casing material, -7000 series aluminum alloy, which improved 60% compared to ordinary aluminum material hardness, density reaches a third of stainless steel, while maintaining a lightweight aluminum material.

 

The processing of titanium composite panels

Processing methods like aluminum composite panels processed form, only because titanium is a titanium metal plate as the surface material, intermediate material to the core material, the substrate can be taken or titanium composite made of stainless steel and other metal composite plate.

Aluminum composite panels are on both sides, aluminum. But its combination of materials titanium composite patterns, each vary, this section shall carry multi-line study was to investigate the user. Taipei Municipal Stadium, but new construction of the first phase of the multi-purpose sports complex patterns is the surface material is titanium, stainless steel back is the Department of Mining. Such a combination of modes of titanium composite board has yet to produce material deformation, thermal expansion and contraction will cause the titanium core material separation. The current local buildings, with the use of performance, system to 4mm titanium composite panels, the combination patterns is a schematic diagram below.

The details of titanium metal plate processing

In the form of titanium metal plate processing with titanium composite board processing it is different. In simple terms, titanium metal wood processing similar to aluminum or stainless steel plate. The process is substantially identical thereto, except the condition of the welding factors vary, titanium metal has environmental constraints (such as an inert gas atmosphere) and welding consumables and equipment also must consider which may refer to AWS D1. 9 / D1 at welding. 9M-2007, Structural Welding Code – Titanium.

To understand 0.6mm titanium material plus performance, had its pre-construction materials for the manufacture Cardcase appearance,to confirm its size workability and bending effects. In this the article may be processing methods buildings, probably can be used, except sit whether the material and machinery equipment size can match. Of course, materials processing costs should remain cautious in the selection by the firms themselves, control costs, quality and quantity of material loss.
