Introduction:

An alloy based on aluminum with a certain amount of other alloying elements is one of the light metal materials. In addition to the general characteristics of aluminum, aluminum alloy has some specific characteristics of alloys because of the different types and quantities of alloying elements added. The density of aluminum alloy is 2.63 ~ 2.85 g/cm3, and it has high strength (σb is 110 ~ 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 plastic workability, good electrical and thermal conductivity, good corrosion resistance and weldability, and can be used as structural materials, and is used in aerospace, aviation, transportation, construction, electromechanical, and other fields.
