5252 Aluminum Alloy Plate


5052 aluminum alloy belongs to the Al-Mg series alloy and has a wide range of applications, especially in the construction industry, which is inseparable from this alloy. It is the most promising alloy. Good corrosion resistance, excellent weldability, good cold workability, and medium strength. The main alloying element of 5052 aluminum alloy is magnesium, which has good forming performance, corrosion resistance, weldability, and medium strength. It is used to manufacture aircraft fuel tanks, oil pipes, and sheet metal parts of transportation vehicles and ships, meters, street lamp brackets, and Rivets, hardware products, electrical appliances, etc.

5052 aluminum alloy is the most widely used anti-rust aluminum. This alloy has high strength, especially fatigue resistance: it has high plasticity and corrosion resistance and cannot be strengthened by heat treatment. It has good plasticity during semi-cold work hardening, cold work When hardened, the plasticity is low, the corrosion resistance is good, the weldability is good, the machinability is poor, and it can be polished. Uses are mainly used for low-load parts that require high plasticity and good weldability, working in liquid or gaseous media, such as fuel tanks, gasoline or lubricating oil pipes, various liquid containers and other small-load parts made by deep drawing: Wire is used to make rivets.

The machinability of the aluminium / aluminum 5252 alloy is poor when compared with other aluminium / aluminum alloys. If machining is performed, lubricating oil must be used. However, the finish tends to be ‘gummy’.


The aluminium / aluminum 5252 alloy can be hot and cold formed very easily.


The aluminium / aluminum 5252 alloy is weldable using commercial welding methods. The preferred methods are TIG and /or MIG. Brazing method is not suitable.


The aluminium / aluminum 5252 alloy is forgeable from 510 to 371°C (950 to 700°F).

Hot Working:

The aluminium / aluminum 5252 alloy can be hot worked if required in the range of 482°C (900°F) down to 260°C (500°F).

Cold Working:

The aluminium / aluminum 5252 alloy can be easily cold worked using the conventional methods. It is suited for cold forming by blanking, drawing, or bending.


The aluminium / aluminum 5252 alloy can be annealed at 343°C (650°F) and then air cooled.


The aluminium / aluminum 5252 alloy can be hardened by cold working only.


The aluminium / aluminum 5252 alloy is widely used in the manufacture of automotive trim and appliances.
