Aluminum alloy has low density, but relatively high strength, close to or exceeds high-quality steel, good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, and is widely used in industry.

According to the processing method, aluminum alloys can be divided into two categories: deformed aluminum alloys and cast aluminum alloys:

Deformed aluminum alloy can withstand pressure processing. It can be processed into various shapes and specifications of aluminum alloy materials. Mainly used for manufacturing aviation equipment, doors and windows for construction, etc. Deformable aluminum alloys are divided into non-heat treatable strengthened aluminum alloys and heat treatable strengthened aluminum alloys. The non-heat-treated reinforced type cannot be improved by heat treatment, but can only be strengthened by cold working deformation. It mainly includes high-purity aluminum, industrial high-purity aluminum, industrial pure aluminum, and rust-proof aluminum. The heat-treatable aluminum alloy can be improved by mechanical treatment such as quenching and aging. It can be divided into hard aluminum, forged aluminum, super hard aluminum and special aluminum alloy.

Cast aluminum alloys can be divided into aluminum-silicon alloys, aluminum-copper alloys, aluminum-magnesium alloys, aluminum-zinc alloys, and aluminum rare-earth alloys according to their chemical composition. Among them, aluminum-silicon alloys have eutectic silicon-aluminum alloys, eutectic silicon-aluminum alloys, and single alloys. Crystal silicon aluminum alloy, cast aluminum alloy is used in the as-cast state.
