2A14 belongs to both hard aluminum alloy and wrought aluminum alloy in terms of composition. Compared with 2A50, due to the higher copper content, it has higher strength and better thermal strength, but its plasticity in hot state is not as good as 2A50. It has good machinability, good contact welding, spot welding and seam welding performance, poor arc welding and gas welding performance; heat treatment can be strengthened, with extrusion effect; corrosion resistance is not high, and there is a tendency for inter-inspection corrosion during artificial aging. Therefore, the longitudinal and transverse properties are different; the corrosion resistance is not high, but the tendency of intergranular corrosion and stress corrosion cracking in the artificial aging state.
