Common corrosion forms of titanium alloy

Titanium alloy

Titanium alloy has a low density, high strength, corrosion resistance, good process performance, etc., it is ideal aerospace engineering (34.27, 0.85, 2.54%) structural materials. In the actual production environment, different types of corrosion will occur, Detect-Metals will introduce the common corrosion forms of titanium alloy, mainly the following categories:

1, crevice corrosion

Gaps in metal structures or defects, due to the stagnation of the electrolyte constitute an electrochemical cell and cause localized corrosion in neutral and acidic solution, contact corrosion occurs at the gap is much greater than the probability of titanium alloy alkaline solution, contact corrosion does not occur Throughout the slit surface, but eventually lead to local perforation damage.

2, pitting

In most titanium salt solution without pitting, which occurred in a non-aqueous solution and high boiling concentrated chloride solution, the solution of halide ions on the surface of the passivation film is etched titanium, titanium internal diffusion to occur pitting , pitting diameter less than its depth. Some organic medium and titanium alloy pitting phenomenon will occur in the halogen solution, titanium alloy pitting halogen solution generally occurs at high concentrations high temperature environment, in addition, sulfide and chloride pitting require specific conditions and limited.

3, hydrogen embrittlement

Hydrogen embrittlement (HE), also known as hydrogen induced cracking or hydrogen damage, is one of the early damage Failure titanium alloy, titanium and titanium alloy surface passivation film has a high intensity, sensitive to hydrogen embrittlement increases with the intensity increases, the passivation film is sensitive to hydrogen embrittlement.

4, contact corrosion

Titanium oxide surface passivation film of titanium alloy potential toward a positive potential to promote and improve the corrosion resistance of titanium acid and aqueous medium. Due to the high potential of the titanium surface, it will inevitably result in the formation of other metals in contact with an electrochemical circuit caused by contact corrosion. Titanium alloy prone to contact corrosion in the following types of media: the first is water, saline solution, water, air, HNO3, acetic acid, etc., stable electrode potential of the solution Cd, Zn, Al is more negative than Ti, anode corrosion 6 to 60 times the rate of proliferation of said second type is H2SO4, HCl, etc., Ti in these solutions may be in the passive state, it may be in the activation state, the actual contact corrosion is common during the first class solution corrosion. Usually anodized layer on the substrate surface modified form, hindering contact corrosion.


5 Tips you need to learn before welding aluminum

welding aluminum
Preweld cleaning requires two operations: oil/grease removal and oxide removal. As below, remove oils and greases first, then remove the oxide. Don’t reverse this order.

Take the following 5 tips before welding aluminum:

1. Remove oil, grease, and water vapor using an organic solvent such as acetone or a mild alkaline solution like a strong soap. You may also use citrus-based degreasers, but be sure to rinse and dry the part before welding.
2. Remove surface oxides with a stainless steel wire brush (used only for aluminum) or strong alkaline or acid. Many welding suppliers sell oxide-removal solutions in spray or squeeze bottles for local application. Exercise extreme care when handling these solutions, and again, rinse and dry the part before welding.

3. Assemble the joint. If it won’t be welded immediately, cover the joint with brown Kraft paper to prevent dirt and grit in the air from getting into the joint.

4. Keep the aluminum dry and at room temperature.

5. Weld within a few days. Clean the joint again if it isn’t welded within that time.

what is aluminum?

what is aluminum

Aluminium is the most widely used non-ferrous metal. Global production of aluminium in 2005 was 31.9 million tonnes. It exceeded that of any other metal except iron (837.5 million tonnes). Forecast for 2012 is 42–45 million tonnes, driven by rising Chinese output.

Since Aluminium is in our life evrywhere, what is aluminum?

Aluminium is a relatively soft, durable, lightweight, ductile and malleable metal with appearance ranging from silvery to dull gray, depending on the surface roughness. It is nonmagnetic and does not easily ignite. A fresh film of aluminium serves as a good reflector (approximately 92%) of visible light and an excellent reflector (as much as 98%) of medium and far infrared radiation. The yield strength of pure aluminium is 7–11 MPa, while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa. Aluminium has about one-third the density and stiffness of steel. It is easily machined, cast, drawn and extruded.

How to cut thick aluminum sheet?

thick aluminum sheet      aluminum sheet

Do you know how to cut thick aluminum sheet? what is thick aluminum sheet? Thick aluminum sheet refers to aluminum plates thicker than 3 mm. Thick aluminum plate divided into special thick aluminum and the thick aluminum. Special thick aluminum is the thickness of not less than 50 mm of aluminum. Special thick aluminum is mainly used in shipbuilding, boiler, pressure vessel housing beams and the like.

Thick aluminum plate and aluminum sheet metal is substantially the same. In all aspects of products, in addition to aluminum bridge, aluminum boiler, automobile manufacturing aluminum, aluminum pressure vessel and other varieties of multi-layer aluminum pressure vessel is purely slab outside, some species such as automobile frames aluminum (thickness of 2.5 to 10 mm), the pattern aluminum (thickness of 2.5 to 8 mm), stainless aluminum, heat-resistant aluminum sheet and other varieties of the same cross.

So how to cut thick aluminum sheet? There are two nice methods here:

1- flame cutting, cheap and fast, but cutting precision aluminum susceptible to bias and uneven heat deformation.

2- waterknife cutting, more expensive, speed is relatively slow, the accuracy is not very bad, basically negative 2mm.(The so-called “water knife”, is sealed with a high-pressure pump the water pressure through a nozzle made of very fine nozzle advanced carbide, sapphire, diamond and other discharge, cutting material. Some water also joined a number of long-chain polymers, such as polyethylene oxide, increased water “viscosity”.)




7075 aluminum plate require high strength than other aluminum plate


7xxx series aluminum is aluminum industry’s high-end products, 7xxx line aluminum containing mainly zinc. It belongs to the aviation series, aluminum-magnesium zinc copper alloy. Heat treatable, it is super-hard alloy, good wear resistance. 7xxx series alloys more used aircraft materials, in recent years, ski poles, golf club and other sporting goods, also used to produce this alloy.

This alloy to alloy represented 7005,7020,7075, mainly in the following three features:

One, better physical properties, compared with the 5083 aluminum plate , manufactured extruded profile is easy, workability and corrosion resistance is also good, can be obtained using the age hardening high strength; as heat treated 7075 aluminum plate, multi-T651, this treatment can be residual stress after T6 treatment, the correct and uniform stretching to prevent deformation of the workpiece during machining distortion occurs. T73 treatment, mechanical properties will be reduced, but there is a tendency to reduce the effects of stress corrosion.

Second, even the natural aging, 7xxx alloys can reach a very high strength, low sensitivity to crack;

Third, the heat-affected part of the welding, since the heating is solid melts, it later when natural aging, can restore strength, thereby increasing the strength of the welding seam. Such alloys are widely used in the manufacture of welded components.

Because 7xxx series alloys require high strength, corrosion resistance can be strong, now basically rely on imports, China’s production process to be improved.

DETECT-METALS Aluminum As the aluminum industry leader since its inception in 1997, specialized in aluminum foil production and sales, has accumulated rich experience in the industry in the area. Future, Aluminum will continue to expand further, in-depth reform, and actively explore the transformation and upgrading of the aluminum industry.

Aluminum pipe weight calculation method


Many friends new entrants to the aluminum business scopy , it’s generally do not know the weight of aluminum pipe calculated, in fact, there is a weight aluminum pipe formula can be set, usually under the designation investigation Materials Handbook, calculated according to the proportion of the volume *  seek. as follows:

Aluminum pipe weight formula = (OD – Wall Thickness) *wall  thickness * 0.00879 * length.
Because aluminum pipe is usually an alloy. The actual weight is slightly larger than the theoretical calculation.

For Example: diameter 28mm, wall thickness 3mm, length of 2 m, what’s the weight of this 2024 aluminum pipe ?


(Outer diameter 28mm- wall thickness 3mm) * wall thickness of 3mm * Density factor 0.00879 * length 2m = weight of 1.32 kg of aluminum tubing.
In this explanation, the number of units of the formula, please note, in practical industrial applications, outside diameter and wall thickness of the tubes are generally measured in millimeters, the outer diameter is 28 mm, wall thickness of 3 mm, The median number of conversion can be directly used, specifically to talk about is the length, in fact, we can also be converted into length mm to count, that is 2,000,000 mm 2 meters, if we used the actual calculation are used to calculate the millimeter, then the out After dividing the weight value 1,000,000 fine. This is everyone’s computing like it!

how can we distinguish the fake or real aluminum alloy fastly?

Since more and more aluminum alloy products appear after another, it’s not easy to tell when we select it, a lot of unscrupulous manufacturers took the opportunity to make trouble, aluminum alloy mixed fish heads on the market, real to the enemy, indeed a headache for consumers. But how can we distinguish the fake or real aluminum alloy fastly?

1. There are two sides of aluminum alloy:sub-sided and single-sided.

2. At the time of purchasing it,you need to observe its surface and color, whether the appearance is smooth, the color is gorgeous.

3. aluminum alloy glue seam neat, decorative aluminum plate when building exterior, between the plates must usually have a slit width.

4. If the appearance of aluminum alloy with deform and dark,these are defective.

5. You can analyze aluminum alloy, the primary problem is on the bottom of the aluminum plate , the dealer would recommend that you purchase the underlying data is the high-density wood panels and more similar. It’s outdoor use, their life is very weak, will deform easily after wind, sun and rain. The underlying data are already deformed, do not be fooled by dealers, must hold what you want to buy.

How to clean pattern aluminum plate professionally?

Pattern aluminum plate in life is becoming more common, and the role of pattern aluminum is also growing, after the washing process will become more beautiful pattern aluminum alloy in the production process will often appear loose ingot or blowhole and other defects, to the production process of a lot of trouble. Following small and you a brief introduction pattern aluminum plate washing deal with it, how to be more professional washing pattern aluminum plate.

Start porosity is concerned, it is mainly among aluminum ingot circular hole, the reason is mainly formed when dissolved gas is always in a state of saturation, and the melt, there are still a lot of non-metallic inclusions It slows things, so that the gas in the process of casting floating rate, bubbles will remain in the pores of the ingot.

Loose ingot form factors are two: First, there is no removal of loose melt gases; the second is a loose contraction generated when it is related to gas and melt, generally when we conduct analysis mainly based on gas content of the melt and the casting speed.

In fact, we can also use a liquid feeding mode, so it reduces the metal in the furnace residence time, can make the inside of the gas furnace in the continuous saturation effect to get a good release and decomposition, but also good control generation of impurities, reduce non-metallic slag material.

1, after alkaline etching, the aluminum plate surface pattern will be left Dalian alkaline etching grooves film, which we call water alkaline etching after. Pattern aluminum plate base after etching is more difficult to clean, and first of all we want in favor of cleaning products point of view, the first tank to maintain the temperature of the water and alkaline water is not going to replace. After washing twice, in order to make a better cleaning effect, we can be appropriately stirred. After washing twice watching work How much amount may be, it can not handle the overflow.

2, it is necessary to go through at least two water washing step is called neutralized. This washing we recommend using circulating water cleaning, doing so in order to protect normal oxidation tank when, because in and the nitric acid tank, if it is brought into the oxidation tank, then there may not form an oxide film, or an increase in the oxidation tank impurities, this will accelerate the aging of the oxidation tank.

3, a simple two washing, washing after chemical polishing after chemical polishing will be from some residual liquid, in order to better clean, small second sink recommend using circulating water, the first water tank maintained at a temperature on the line.
