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 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 alloy, aluminum copper alloy, aluminum magnesium alloy, aluminum zinc alloy and aluminum rare earth alloy according to chemical composition. Crystal silicon aluminum alloy, cast aluminum alloy is used in the as-cast state. Some aluminum alloys can use heat treatment 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 secondary alloying elements are nickel, iron, titanium, chromium, and lithium.
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, widely used in industry, the amount of use is second only to steel .
