Aluminum alloy has good conductivity, thermal conductivity, corrosion resistance and weldability; It is widely used in solar electronic paste, conductive and anti-corrosion metal coating, aerospace equipment, rail structure, automobile parts and so on. In addition to the general characteristics of aluminum, aluminum alloy powder has some specific characteristics of alloy according to the type and quantity of alloying elements. If the strength is high, the specific strength is close to that of high alloy steel, and the specific stiffness is higher than that of steel, it has good castability and plasticity, and can be used as structural material.
