Aluminum alloy housing has many advantages. Aluminum alloys have high strength, specific modulus, fracture toughness, fatigue strength and corrosion resistance stability. The aluminum alloy material has a low density, no magnetic resistance, low temperature alloy phase, the magnetic field resistivity is small, the gas is good, and the induction radiation can be faster. It has been widely used in aviation, aerospace, high-speed trains, lithium-ion battery case, mechanical manufacturing, ships and chemical industries.
The main alloy element of the aluminum alloy housing is magnesium and silicon, which has excellent processability, weldability, extrudability, and electroplating, good corrosion resistance, toughness, easy polishing, coloring film, and excellent anode. The oxidation effect is a typical extrusion alloy.
