The difference between the two is not big from the point of view of oxidation, and the main difference is in mechanical properties. In terms of tensile strength and yield strength, 5083 aluminum plate is much stronger than 5052 aluminum plate.
Their chemical composition is as follows:
5052 Si 0+ Fe0.45 Cu0.1 Mn0.1 Mg2.2-2.8 Cr0.15-0.35 Zn 0.1
5083 Si 0.4 Fe0.4 Cu0.1 Mn0.3-1.0 Mg4.0-4.9 Cr 0.05-0.25 Zn 0.25
Features and uses are as follows:
5052 alloy aluminum plate has good formability, corrosion resistance, candleability, fatigue strength and moderate static strength. It is used to manufacture aircraft fuel tanks, fuel pipes, and sheet metal parts of transportation vehicles and ships,instruments, hardware products, street lamp brackets and rivets, etc.
5083 alloy aluminum plate is used in occasions requiring high corrosion resistance, good weldability and medium strength, such as welding parts of ships, automobiles and aircraft plates; pressure vessels, refrigeration devices, TV towers, drilling equipment that require strict fire protection , transportation equipment, missile elements, armor, etc.
5XXX series alloys belong to the more commonly used alloy aluminum plate series, the main element is magnesium, and the magnesium content is between 3-5%. Also known as aluminum-magnesium alloy. The main features are low density, high tensile strength, high elongation and good fatigue strength, but cannot be strengthened by heat treatment. The weight of aluminum-magnesium alloy is lower than other series under the same area. It is also widely used in conventional industries.
