5052 belongs to the Al-Mg series alloy and is widely used. Especially in the construction industry, this alloy is inseparable and it is a promising alloy. 

It has good corrosion resistance, excellent corrosion resistance, good cold workability, and has medium strength. The main alloy element of 5052 is magnesium,

 which has good formability, corrosion resistance, and medium strength. It is used to manufacture aircraft fuel tanks, oil pipes, and sheet metal parts of 

transportation vehicles and ships, instruments, street lamp brackets and rivets, hardware products, Electrical appliance casing, etc.

② AL-Mn alloy is a widely used anti-rust aluminum. This alloy has high strength, especially strength: high plasticity and corrosion resistance. 

It cannot be strengthened by heat treatment. It has good plasticity during semi-cold work hardening. When hardened, it has low plasticity, good corrosion resistance, 

machinability, and polishability. It is mainly used for low-load parts that require high plasticity and work well 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 rivet.
