Aluminum Round Tubing Polished 2024(2A12), LY12, LY11, 2A11 Aluminum Pipe Tube China Supplier
2A12 aluminum tube is a kind of high-strength hard aluminum, which can be strengthened by heat treatment; 2A12 aluminum tube has good weldability in spot welding, and has a tendency to form intergranular cracks when gas welding and argon arc welding are used; 2A12 aluminum tube can be cut after cold hardening The performance is still good. The corrosion resistance is not high, and anodic oxidation treatment and painting or aluminum coating are often used to improve the corrosion resistance.
