What is the difference between 3003 aluminium sheet and 5052 aluminium sheet?

What is the difference between 3003 aluminium sheet and 5052 aluminium sheet?

The most common alloy aluminium plate on the market now is 3003 aluminium plate and 5052 aluminium plate, which are the two most representative grades of the two series of aluminium plates. Although the use of both is very widespread, but many people are not clear about the difference between the two. The following, to 3003H24 aluminum plate and 5052H24 aluminum plate as an example, to popularize the knowledge of this area.

1. from the chemical composition, 3003 aluminum plate is aluminum manganese alloy, the main alloying element is manganese. 5052 aluminum plate is aluminum magnesium alloy, the main alloying element is magnesium. 3003 aluminum plate aluminum content is slightly higher than 5052 aluminum plate.

2. From the mechanical properties, the tensile strength of 3003H24 aluminum plate is 145-195Rm/MPa, while the tensile strength of 5052H24 aluminum plate is as high as 230-280Rm/MPa, much higher than 3003H24 aluminum plate; the elongation strength of 3003H24 aluminum plate is 115Rm/MPa, while the elongation strength of 5052H24 aluminum plate is 150Rm/MPa. Therefore, the performance of 5052 aluminum plate is significantly better than 3003 aluminum plate.

3. From the common specifications, 3003 aluminium sheet is mainly used in thin plate, and thick plate is not much used; while 5052 aluminium sheet is widely used in addition to thin plate and thick plate.

4. From the scope of application, 3003 aluminium sheet is mainly used in wet environments, such as product packaging, refrigerators, air conditioners, cold storage, ventilation ducts and so on. And 5052 aluminium sheet is commonly used in electrical shells, transportation vehicles, pressure vessels, etc. It is a common material for manufacturing automobile and aircraft fuel tanks and oil pipes.

5. From the price of aluminum plate, 3003 aluminum plate is slightly higher than the price of pure aluminum plate, while 5052 aluminum plate is significantly higher than 3003 aluminum plate. Depending on the specification and thickness, the price of a ton of 5052 aluminium sheet is about 300 USD higher than the price of a ton of 3003 aluminium sheet.

Although 3003 aluminium sheet and 5052 aluminium sheet are often used as rust-proof aluminium, the difference between the two types of aluminium sheet is still very obvious, and companies must choose the right product according to their production needs.
