Aluminum alloy has low density, but its strength is relatively high, close to or higher than that of high-quality steel. Good plasticity, can be processed into various profiles, and has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its usage is second only to steel. Some aluminum alloys can obtain good mechanical properties, physical properties and corrosion resistance through heat treatment. Hard aluminum alloy belongs to al-Cu-Mg system, generally containing a small amount of Mn, which can be strengthened by heat treatment. It is characterized by high hardness but poor plasticity. Ultra-hard aluminum belongs to Al-Cu-Mg-Zn system and 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 softens quickly at high temperature. Deformed aluminum alloy is mainly aluminum-zinc-magnesium-silicon alloy.
