Through long-term production practices and scientific experiments, people gradually add alloy elements and apply heat treatment and other methods to strengthen aluminum, so that a series of aluminum alloys are obtained. The alloy formed by adding certain elements has higher strength while keeping the advantages of light weight of pure aluminum and the like, and the sigma b values can respectively reach 24-60 kgf/mm 2. Therefore, the specific strength (the ratio sigma b/rho of the strength to the specific gravity) of the composite material is superior to that of a plurality of alloy steels, so that the composite material becomes an ideal structural material and is widely applied to the aspects of mechanical manufacture, transportation machinery, power machinery, aviation industry and the like, and fuselages, skins, air compressors and the like of airplanes are often manufactured by aluminum alloy to reduce the dead weight.
