It is used to manufacture aircraft structures and other high-stress structural parts that require high strength and high corrosion resistance, such as aircraft upper and lower wing panels, purlins, and partitions. After solution treatment, the plasticity is good, the heat treatment strengthening effect is particularly good, the strength is below 150 ° C, and the low temperature strength is particularly good, the welding performance is poor, the stress corrosion cracking tendency is tendency, and the double-stage aging can improve the anti-SCC performance.
