The shell is stamped with aluminum alloy material, which has the characteristics of good ductility, low density, electrical conductivity, heat transfer, corrosion resistance, and beautiful appearance.

Metal aluminum shells are widely used in instruments, meters, electronics, communications, automation, sensors, smart cards, industrial control, machinery and other industries. The aluminum alloy shell is an ideal shell for instrument packaging. The surface treatment adopts electrostatic spraying, and the colors are off-white, dark gray, black, army green, etc.

The conductivity of aluminum is second only to silver and copper. Although its conductivity is only 2/3 of copper, its density is only 1/3 of copper. Therefore, for the same amount of electricity, the mass of aluminum is only half of the mass of copper. The oxide film on the aluminum surface not only has corrosion resistance, but also has insulation properties, and is also used in lithium battery casings.

Aluminum alloy can not only become an ideal instrument package shell, but also an important accessory for the space shuttle.

Aluminum alloy is the main material used in the manufacture of aircraft. Compared with the mild steel used in automobile manufacturing, aluminum alloy is expensive and has a low density. The relative density is 2.8. Compared with the relative density of mild steel of 7.8, it is about one-third lighter. Although the strength is similar, it is the material for airplanes. Lightness is the most important thing, and it has strong corrosion resistance and convenient processing. Therefore, aluminum alloy is the most ideal material for making airplanes.
