Compared with 2A50, due to the higher copper content, the strength is higher and the thermal strength is better, but the plasticity in the hot state is not as good as that of 2A50. , 2014 aluminum alloy has good machinability, good contact welding, spot welding and roll welding performance, and poor arc welding and gas welding performance; it can be strengthened by heat treatment and has extrusion effect.
Applicable to occasions requiring high strength and hardness (including high temperature). Aircraft heavy duty, forgings, plate and extruded materials, wheels and structural elements, multi-stage rocket first stage fuel tanks and spacecraft parts, truck frames and suspension system parts.
