2A14 is a hard aluminum alloy and a wrought aluminum alloy in terms of composition. 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 2A50. Alloy It has good machinability, good performance of contact welding, spot welding and roll welding, and poor performance of arc welding and gas welding; it can be strengthened by heat treatment and has squeezing effect; corrosion resistance is not high, and there is a tendency to check corrosion during manual aging. Therefore, the longitudinal and lateral properties are different; the corrosion resistance is not high, but the tendency of intergranular corrosion and stress corrosion cracking in the artificial aging state.
