Magnesium alloy The main ingredient is magnesium alloy. Magnesium takes 90%, followed by aluminum accounted for 9%, plus 1% zinc. Generally speaking, the hardness of magnesium alloy is several times ABS engineering plastics, but weighs only one-third of plastic, coupled with its excellent cooling capacity. So it's often used in high-grade ultra-thin or small size laptop shell. Moreover, the silver magnesium alloy makes product more attractive and fashionable. And it's easy to dye. With surface coating process, it can be customized into a variety of colors, to add much color to notebook computer, which is beyond the engineering plastics and carbon fiber. Therefore magnesium alloy is the preferred portable notebook shell material. However, magnesium alloy is not very erasing resistant. After long time using,the color of the shell will turn dark. And spray painting over the product is vulnerable to scratch and fall off. Because of the high cost, and dedicated processing, it's more difficult to model than ABS. So laptop generally applied to aluminum-magnesium alloy on the top cover or the palm rest part of the roof. There is little product to use aluminum-magnesium alloy manufacture of the whole. Advantages: high strength, light weight, good heat dissipation. Disadvantages: high cost of spray paint to wear. Carbon Fiber Carbon fiber material is a very interesting material; both have strong features of aluminum-magnesium alloy, but also the high plasticity of ABS engineering plastics. It looks like plastic, but the strength and thermal conductivity are better than ordinary ABS plastic. And carbon fiber is a conductive material which can play a role similar to the metal shield (ABS shell plating the inner surface of the need for another layer of metal film to shield). Strength and toughness of carbon fiber is twice the aluminum-magnesium alloy, and good heat dissipation performance. The drawback is the cost of carbon fiber high. It's not easy to model. So the shape of the carbon fiber chassis is generally a lack of relatively simple changes in color and it's hard to model. In addition, another disadvantage is that if the ground is not good, there will be a slight leakage inductance. It requires a layer of insulating coating. Advantages: good heat dissipation, light weight, strength and toughness. Disadvantages: high cost, the appearance of monotonous.
