Aluminum alloy

An alloy based在铝a certain amount of other alloying elements is one of the light metal materials. In addition to the general characteristics of aluminum, aluminum alloys have some specific characteristics of alloys due to the different types and quantities of added alloying elements. The density of aluminum alloy is 2.63～2.85g/cm, it has high strength (σb is 110～650MPa), the specific strength is close to that of high alloy steel, the specific stiffness is higher than that of steel, it has good casting performance and plastic processing performance, and good electrical conductivity. , Thermal conductivity, good corrosion resistance and weldability, can be used as structural materials, has a wide range of applications in aerospace, aviation, transportation, construction, electromechanical, light and daily necessities.
