What Does Aluminum Belong To?

Aluminum alloy belongs to non-ferrous metal structure material.

Aluminum alloy density is low, but the strength is relatively high, close to or more than high quality steel, good plasticity, can be processed into a variety of profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, the amount of use is second only to steel. Some aluminum alloys can be heat treated to obtain good mechanical, physical and corrosion resistance.

Duralumin alloy belongs to AI -- Cu -- Mg system, generally contains a small amount of Mn, can be heat treated to strengthen. It is characterized by high hardness but poor plasticity. Superduralumin belongs to Al-Cu-Mg-Zn system, which can be strengthened by heat treatment. It is the aluminum alloy with the highest strength at room temperature, but it has poor corrosion resistance and fast softening at high temperature.

Forged aluminum alloy is mainly Al-Zn-Mg-Si alloy, although there are many kinds of elements, but the content is small, so it has excellent thermoplastic, suitable for forging, so it is also called forged aluminum alloy.
