2A14 aluminum plate belongs to hard aluminum alloy, so it has high strength, good thermal strength, good machinability, good electrical resistivity, spot welding and seam welding performance, can be strengthened by heat treatment, and has extrusion effect. Therefore, there are differences in longitudinal and transverse performance.
