Aluminum alloy is an alloy based on aluminum with a certain amount of other alloying elements, and it is one of the light metal materials.
The alloy based on aluminum and containing some other alloying elements is a light metal material. In addition to the general characteristics of aluminum, aluminum alloy has some special characteristics because of the different types and quantities of alloying elements added. The density of aluminum alloy is 2.63 ~ 2.85 g/cm, its strength is high (σb is 1 10 ~ 650 MPa), its specific strength is close to that of high alloy steel, and its specific stiffness exceeds that of steel. It has good castability and plasticity, good electrical and thermal conductivity, good corrosion resistance and weldability, and can be used as a structural material.
