Aluminum Alloy Material Properties
The aluminum alloy has low density, good plasticity ,but high strength, which is close to or exceeds high-quality steel. The aluminum alloy that can be processed into various profiles has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry and second only to steel. . Some aluminum alloys can have heat treatment to achieve good mechanical properties, physical properties and corrosion resistance. Hard aluminum alloy belongs to AI-Cu-Mg system, generally contains a small amount of Mn, which can be heat treated and strengthened. It is characterized by high hardness but poor plasticity. Superhard aluminum is a Cu-Mg-Zn system, which can be heat-treated and strengthened. It is the highest strength aluminum alloy at room temperature, but has poor corrosion resistance and high temperature softening. The wrought aluminum alloy is mainly an Al-Zn-Mg-Si alloy. Although it has many kinds of elements, it has a small content, so it has excellent thermoplasticity and is suitable for forging, so it is also called forged aluminum alloy.
