Product name eight

2A14 belongs to both hard aluminum alloy and forged aluminum alloy in terms of composition. Compared with 2A50, 2A14 has higher strength and better thermal strength due to its high copper content, but its plasticity in hot state is not as good as 2A50. The 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; The corrosion resistance is not high, and there is a tendency of inter inspection corrosion during artificial aging.
