2A12 Aluminum Rod
2A12 aluminum rod is a kind of high-strength hard aluminum which can be heat-treated and strengthened. It has moderate plasticity and pot weldability and it has a tendency to form intergranular cracks when using gas welding and argon arc welding in annealing, quenching and hot state. The alloy is quenched. After quenching and cold-working hardening, its machinability is good, but it is not good in the annealed state. Due to its corrosion resistance is not high, we often adopt anodizing treatment and painting method or the surface coated with an aluminum layer to improve the corrosion resistance.

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.
