Background
Aluminum alloy is a non-ferrous metal structural material which is most widely applied in industry, and is widely applied in the industries of aerospace, automobiles, mechanical manufacturing, ships and the like.

Cu can improve the strength of the alloy and improve the high-temperature performance of the alloy, but the corrosion resistance and the casting performance of the alloy are reduced due to the excessively high Cu content.
Zn can improve the solubility and the dissolution speed of Cu in the aluminum alloy so as to improve the plasticity of the alloy, and can also form a strengthening phase Mg/Zn with Mg2And the tensile strength and the yield strength of the alloy are enhanced.
Zr plays a role in refining grains, the chemical properties of Hf and Zr are close, the corrosion resistance of Zr is close to those of Nb and Ta, and Sr can improve the plastic processability of the alloy.
