Prodsuct Introdsuction
2A02 aluminum bars is a hard aluminum with high strength, high strength at room temperature, and high heat strength, belonging to heat-resistant hard aluminum. The alloy has high plasticity during hot deformation. In the extruded semi-finished prodsuct, there is a tendency to form a coarse crystal ring, which can be heat-treated and strengthened, and used in quenching and artificial aging conditions.
