2A12 aluminum alloy rod is a kind of high-strength hard aluminum, which can be heat-treated and strengthened; 2A12 aluminum alloy has good spot weldability, and there is a tendency to form intergranular cracks when using gas welding and argon arc welding; 2A12 aluminum alloy can be cooled after hard work Cutting performance is still good. 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.
2A12 aluminum round bar rod is maily used in fields requiring high strength and hardness (including high temperature). Heavy forgings, slabs and extruded materials for aircraft structural parts, multi-stage rocket first-stage fuel tanks and spacecraft parts, wheels, truck frames and suspension system parts.
