2A06 T4 T6 hard aluminium square flat bar

2A06 T4 T6 hard aluminium square flat bar is a high-strength duralumin, with the same press work ability and machinability as 2A12, and good plasticity in annealed and just-quenched states. The alloy can be quenched and aged, and the general corrosion stability is the same as that of 2A12. When heated to 150 to 250 °C, the tendency to form intergranular corrosion is smaller than that of 2A12. The weld ability of spot welding is the same as that of 2A12 and 2A16. As good, but worse than 2A16.
