Aluminum alloy processing methods 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 in the manufacture of aviation equipment, construction windows and doors. Deformed aluminum alloys are divided into non-heat-treatment-reinforced aluminum alloys and heat-treatment-reinforced aluminum alloys.
The non-heat-treatment-reinforced type cannot improve mechanical properties through heat treatment, and 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-treatment-reinforced aluminum alloys can be improved in mechanical properties through heat treatment methods such as quenching and aging. It can be divided into hard aluminum, wrought aluminum, super-hard aluminum, and special aluminum alloys.
According to chemical composition, cast aluminum alloys can be divided into aluminum-silicon alloys, aluminum-copper alloys, aluminum-magnesium alloys, aluminum-zinc alloys, and aluminum-rare earth alloys. 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. Some aluminum alloys can be heat treated to obtain good mechanical properties, physical properties and corrosion resistance.
Aluminum alloy is a general term for aluminum-based alloys. The main alloying elements are copper, silicon, magnesium, zinc, and manganese, and the minor alloying elements are nickel, iron, titanium, chromium, and lithium.
Aluminum alloy has low density but high strength. It is close to or exceeds high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its usage is second only to steel.
