3A21 Aluminum Round bar

3A21 aluminum alloy round bars are a widely used rust-resistant aluminum material, belonging to the 3000 series aluminum-manganese alloys. They possess excellent corrosion resistance, weldability, and plasticity.
Chemical Composition: Manganese (1.0-1.6%) is the main alloying element, with copper content strictly limited to ≤0.2%. Other elements include silicon, iron, and titanium.
Mechanical Properties: Tensile strength 120-160 MPa, conditional yield strength ≥85 MPa, elongation in the annealed state reaching 20%-30%.
Processing and Welding: Cannot be strengthened by heat treatment; strength is improved through cold working. Weldability is good, but resistance welding is required when the copper content exceeds 0.2%
