Main features and application scope: This is a high-strength hard aluminum that can be strengthened by heat treatment. It has medium plasticity in the quenched and freshly quenched states, and is spot welded. Good. There is a tendency to form intergranular cracks when gas welding. The machinability of the alloy is good after quenching and cold work hardening. The machinability after annealing is low: the corrosion resistance is not high. Anodizing and painting methods are often used or An aluminum layer is added to the surface to improve its corrosion resistance. It is mainly used to make various high-load parts and components (but not stampings and forgings) such as aircraft skeleton parts, skins, partitions, ribs, spars, rivets and other working parts below ℃.
