Aluminum alloy aluminum plate is a typical hard aluminum alloy in the aluminum-copper-magnesium series. Its composition is relatively reasonable and its overall performance is good. This alloy is produced in many countries and is the most widely used among duralumin. The alloy is characterized by high strength and certain heat resistance, and can be used as working parts below ℃. When the temperature is higher than ℃, the strength of the alloy is higher than that of the alloy. The formability is relatively good in the hot state, annealed and newly quenched states, and the heat treatment strengthening effect is significant, but the heat treatment process requirements are strict. The corrosion resistance is poor, but it can be effectively protected by coating with pure aluminum. It is easy to crack during welding, but it can be welded or riveted using special technology. Widely used in aircraft structures, rivets, truck wheels, propeller components and other structural parts.

● Characteristics and scope of application
Aluminum alloy is a kind of high-strength hard aluminum that can be strengthened by heat treatment. It has medium plasticity in annealing, fresh quenching and hot conditions. Aluminum alloy spot welding has good weldability, and it can be used with gas welding and argon arc welding. There is a tendency to form intergranular cracks. The machinability of aluminum alloys is good after quenching and cold work hardening, but poor in the annealed state. The corrosion resistance is not high, and anodizing and painting methods are often used, or an aluminum layer is added to the surface to improve corrosion resistance.
●Application
It is mainly used to make various high-load parts and components (but not stampings and forgings) such as frame parts, skins, bulkheads, wing ribs, wing spars, etc. on aircraft. Rivets and other working parts below ℃.
