The deformed aluminum alloy can withstand pressure processing. It can be processed into aluminum alloy materials of various shapes and specifications. Mainly used in the manufacture of aviation equipment, building doors and windows. The deformed aluminum alloy is further divided into a non-heat treatable reinforced aluminum alloy and a heat treatable reinforced aluminum alloy. The non-heat-treated reinforced type cannot be mechanically improved by heat treatment, and 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 reinforced aluminum alloy can be improved in mechanical properties by heat treatment such as quenching and aging, and can be classified into hard aluminum, wrought aluminum, super-hard aluminum, and special aluminum alloy.


Cast aluminum alloy can be divided into aluminum silicon alloy, aluminum copper alloy, aluminum magnesium alloy, aluminum zinc alloy and aluminum rare earth alloy according to chemical composition. Among them, aluminum silicon alloy has hypereutectic silicon aluminum alloy and eutectic silicon aluminum alloy. Crystalline silicon aluminum alloy, cast aluminum alloy used in the as-cast state.


Some aluminum alloys can be heat treated to achieve good mechanical properties, physical properties and corrosion resistance.
