2A12 aluminum bar is a kind of high strength hard aluminum, which can be strengthened by heat treatment.2A12 aluminum bar has good weldability, and has the tendency of forming intercrystalline crack when using gas welding and argon arc welding.The machinability of 2A12 aluminum rod is good after cold working.The corrosion resistance is not high, and the anodic oxidation treatment and painting method or surface coated with aluminum are often used to improve the corrosion resistance.

Typical USES:

2A12 aluminum bar is mainly used for making various parts and components with high load (but not including stamping parts and forging parts), such as aircraft skeleton parts, skin, spacers, wing ribs, wing beams, rivets and other working parts under 150℃.
