Material Name: 2024 Aluminum Alloy Copper Aluminum Alloy
Standard: JIS H4000-1999
Main features and application range: This is a kind of high-strength hard aluminum, which can be heat-treated and strengthened. It has medium plasticity in quenching and quenching conditions. Spot welding is good. There is a tendency to form intergranular cracks during gas welding. The alloy is quenched and After cold work hardening, the machinability is good, and the machinability is low after annealing: the corrosion resistance is not high, and the anodizing treatment and painting method or the surface of the aluminum layer is often used to improve the corrosion resistance. Uses are mainly used to make a variety of high-load parts and components (but not including stampings forgings) such as skeleton parts, skins, partitions, ribs, spars, rivets and other working parts below 150 °C.
