1. مقدمة في 2A14 المواد

      2A14 aluminum alloy is in hard aluminum alloy, and the old grade is LD10. 2A14 has high copper content, high strength, good thermal strength, good machinability, good resistivity, spot welding and seam welding performance, can be heat-treated and strengthened, and has an extrusion effect, but there are differences in longitudinal and transverse properties. The corrosion resistance is not very good, and the intergranular corrosion tendency and stress corrosion and fracture tendency will appear in the artificial aging state.
