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

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

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.
