2A11 aluminum alloy bar rod

2A11 aluminum alloy is a kind of hard aluminum used earliest, which is generally called standard hard aluminum. It has medium strength, good plasticity in annealing, rigid quenching and thermal state, and can be strengthened by heat treatment. It can be used in quenching and natural aging state. It has good spot welding performance, and has a tendency to crack during gas welding and argon arc welding; Machinability is good in quenching and aging state, but bad in annealing state.
