Wrought aluminum alloy can withstand pressure processing. It can be processed into aluminum alloy with various shapes and specifications. It is mainly used for manufacturing aviation equipment, building doors and windows, etc. The deformed aluminum alloy is also divided into non heat treatment strengthened aluminum alloy and heat-treated reinforced aluminum alloy. The non-heat treatment type can not improve mechanical properties 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. Heat treatable and strengthened aluminum alloys can improve mechanical properties by means of quenching and aging. They can be divided into hard aluminum, forged aluminum, superhard aluminum and special aluminum alloys.
