2a14 aluminum belongs to duralumin alloy, so it has higher strength and better heat resistance. It also has good machinability, electrical resistivity, spot and bead welding performance. 2A14 aluminum alloy can be heat treatment, so it has squeezing effect, therefore, vertical and horizontal performance is different. The tensile strength of 2a14 aluminum sheet can be 420MPa, and the elongation is more than 10%. It often used for aerospace, large frame, bridges, large-scale housing, trucks and others.
