2A11 aluminum square bar round bar

2A11 aluminum alloy is the earliest hard aluminum used, generally called standard hard aluminum, with medium strength. It has good plasticity in annealing, quenching and hot state. It can be heat-treated and strengthened. It can be used in quenching and natural aging conditions. The weldability is good, and there is a tendency to crack when performing gas welding and argon arc welding; the cutting is good in the quenching aging state and is poor in the annealing state.
