Introduction of 2A50 forged aluminum block ring bar
2A50 forged aluminum block ring bar has high plasticity in hot state and is easy to forge. Stamping; it can be strengthened by heat treatment, and the strength after quenching and artificial aging is similar to that of duralumin; the process performance is better, but there is extrusion effect, so it is longitudinal It is different from the lateral performance; the corrosion resistance is better, but there is a tendency of intergranular corrosion; the machinability is good, the resistance welding, spot welding, and seam welding performance is good, and the arc welding and gas welding performance is not good.
