The main body of aluminum alloy chassis is made of high-quality aluminum alloy profile, which has the features of sturdy structure, beautiful appearance, good heat dissipation performance, etc. It is widely used in the industries of instruments, meters, electronics, communication, automation, sensors, smart cards, industrial control, precision machinery, etc. It is the ideal case for high-grade instruments and meters. Aluminum alloy is pure aluminum with some alloying elements, such as aluminum-copper alloy, aluminum-zinc-magnesium-copper system of super-hard aluminum alloy. Aluminum alloy has the characteristics of light weight, low cost, mechanical (subject to uniformity of strength), as well as aluminum alloy is easy to process and has a high degree of heat dissipation. Aluminum alloys are particularly suitable for use in vehicle engines. As for the computer chassis used in most of the aluminum-copper alloy. This is mainly because of the heat dissipation problem. Because of the copper and aluminum mixed extrusion manufacturing out, its heat dissipation performance is quite good, and even some high-end CPU water-cooling fan is also the use of this material. If the military, the first choice to ensure is solidity, aluminum - zinc - magnesium - copper system of super hard aluminum alloy is the first choice.
