2024 aluminum alloy is a kind of high-strength hard aluminum alloy, belongs to Al-Cu-Mg system of aluminum alloy, mainly used for making various kinds of high-load parts and components, can be heat-treated and strengthened, and the plasticity is medium in the quenched and just quenched state.
Main characteristics and application scope: It is a kind of high strength hard aluminum, which can be strengthened by heat treatment, and has medium plasticity in quenched and just quenched state. The ability. It is mainly used for making various high load parts and components (but not including stamping forgings) such as aircraft skeleton parts, skins, spacer, wing ribs, wing beams, rivets and other working parts below 150℃.
