2A21 Aluminum Tube
2A12 aluminum Tube 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. After quenching and cold work hardening, the machinability is good and it is not good in the annealed state.

v Since aluminum weighs approximately a third the weight of similar steel section, it is the obvious choice when weight is a factor.
v Excellent resistance to corrosion permits its use without protection in most environments.
v Aluminum’s ability to transmit heat rapidly and efficiently make it an ideal material for the heat transfer processes.
v Aluminum bar can formed readily and has excellent weld ability.
