What is 2024 aluminum alloy
2024 aluminum alloy is a kind of high-strength duraluminum, which belongs to the Al-Cu-Mg series. It is mainly used to make various high-load parts and components. It can be strengthened by heat treatment and has medium plasticity in the quenched and just-quenched state. The corrosion resistance is not high, and anodizing treatment and painting methods are often used to improve its corrosion resistance.
It is mainly used to make various high-load parts and components (but not including stamping forgings), such as air frame, skin, ribs, spars, rivets and other working parts below 150 °C on aircraft.
