aluminium parts in transport aviation

The density of aluminum alloy is 2.63 ~ 2.85g/cm and has high strength（ σ B is 110 ~ 650mpa), the specific strength is close to that of high alloy steel, and the specific stiffness is higher than that of steel. It has good casting performance and plastic processing performance, good electrical and thermal conductivity, good corrosion resistance and weldability. It can be used as structural materials. It is widely used in aerospace, aviation, transportation, construction, electromechanical,...
