Prodsuct advantages

It has high strength, good cutting performance, high strength, heat resistance, good spot welding and remarkable heat treatment strengthening effect, but its corrosion resistance is poor, and cracks are easy to occur during gas welding. Anodic oxidation and coating or surface coating of aluminium are used to improve its corrosion resistance.

Usually used for aircraft skeleton components, rivets, wing beams, truck hub, propeller components, partition frames and other structural parts, as well as working parts within 150 C.
