2A12 Aluminum bar/ rod:
2A12 is a kind of high-strength hard aluminum which can be heat-treated and strengthened. It has medium plasticity in annealing, quenching and hot state. It has good spot welding and good tendency to form intergranular cracks when using gas welding and argon arc welding. The alloy is quenched. After cutting and hardening, the machinability is good and it is not good in the annealed state. The corrosion resistance is not high, and the anodizing treatment and painting method or the surface is coated with an aluminum layer to improve the corrosion resistance.
