Classification Of Processing Methods Of Aluminum Alloys

Aluminum alloys are divided into two categories: cast aluminum alloys, which are used in the as-cast state; and deformed aluminum alloys, which can withstand pressure processing and have higher mechanical properties than the as-cast state. It can be processed into aluminum alloys of various shapes and specifications. Mainly used in the manufacture of aviation equipment, daily necessities, doors and windows for construction, etc.

Aluminum alloys can be divided into deformed aluminum alloys and cast aluminum alloys according to processing methods. Deformed aluminum alloys are further divided into non-heat-treatable-strengthened aluminum alloys and heat-treatable-strengthened aluminum alloys. The non-heat-treatable-enhanced type cannot improve mechanical properties through heat treatment, but can only be strengthened through cold working deformation. It mainly includes high-purity aluminum, industrial high-purity aluminum, industrial pure aluminum, and rust-proof aluminum. Heat-treatable-strengthened aluminum alloys can improve their mechanical properties through heat treatment methods such as quenching and aging. They can be divided into hard aluminum, forged aluminum, super-hard aluminum, and special aluminum alloys. Aluminum alloys can be heat treated to obtain good mechanical properties, physical properties and corrosion resistance. Cast aluminum alloys can be divided into aluminum-silicon alloys, aluminum-copper alloys, aluminum-magnesium alloys and aluminum-zinc alloys according to their chemical composition.
