High-strength wrought aluminum has high plasticity in hot state and is easy to forge. It can be heat-strengthened and strengthened. The strength after quenching and artificial aging is similar to that of hard aluminum. The process performance is better, but there is extrusion effect, so the longitudinal and transverse direction Performance is different; Corrosion resistance is good, but there is a tendency of intergranular corrosion; Good machinability, resistance welding. Spot welding. Seam welding performance is good, arc welding and gas welding performance is not good.
