5052 belongs to the AI-Mg series alloy and is widely used. Especially in the construction industry, this alloy is inseparable and is the most promising alloy. It has good corrosion resistance, excellent weldability, good cold workability, and has medium strength. The main alloy element of 5052 is magnesium, which has good formability, corrosion resistance, weldability, and medium strength. It is used to manufacture aircraft fuel tanks, oil pipes, and metal parts for transportation vehicles and ships, instruments, street lamp brackets, rivets, and hardware. Products, electrical appliance casings, etc. AL-Mn alloy is the most widely used anti-rust aluminum. This alloy has high strength, especially fatigue resistance: high plasticity and corrosion resistance. It cannot be strengthened by heat treatment. It has good plasticity during semi-cold work hardening. , low plasticity when cold work hardened, good corrosion resistance, good weldability, poor machinability, and can be polished. It is mainly used for low-load parts that require high plasticity and good weldability and work in liquid or gas media, such as fuel tanks, gasoline or lubricating oil conduits, various liquid containers and other small-load parts made by deep drawing: Wire is used to make rivets.
