5052 aluminum plate VS 5083 aluminum plate

5052 aluminum plate and 5083 aluminum plate are common aluminum plates in the 5 series aluminum alloy. We will compare and analyze the differences between 5052 aluminum plate and 5083 aluminum plate from the aspects of chemical composition, performance and use, tensile strength, and price.

The difference between 5052 aluminum plate and 5083 aluminum plate

• 1. Chemical composition

5052 aluminum sheet plate: Contains aluminum (Al) as the main element, as well as a small amount of magnesium (Mg) and chromium (Cr).

5083 aluminum sheet plate: Contains aluminum (Al) as the main element, and contains a higher proportion of magnesium (Mg) and a small amount of chromium (Cr).

• 2. Mechanical properties

5052 aluminum plate: Has medium strength and hardness, suitable for general engineering applications.

5083 aluminum plate: Has high strength and hardness, especially suitable for applications with high strength requirements, such as marine engineering.

• 3. Tensile strength

5052: tensile strength (σb): 170～305MPa

5083: tensile strength σb (MPa): 110-136

• 4. Corrosion resistance

5052 aluminum sheet plate: Good atmospheric corrosion resistance, but poor corrosion resistance to strong alkaline media.

5083 aluminum sheet plate: Excellent performance in corrosive media such as seawater, especially suitable for marine engineering and shipbuilding.

• 5. Application areas

5052 aluminum plate: Suitable for general engineering applications, such as automotive parts, aerospace parts, building structures, etc.

5083 aluminum plate: Mainly used in the manufacture of marine engineering equipment, hull structures, LNG tanks and other fields with high requirements for high strength and corrosion resistance.

• 6. Machinability

5052: Good machinability, easy to cut, form and weld.

5083: Due to its higher strength, it has relatively poor processability and may require higher-level tools and equipment.

• 7. Density

5052: It has a lower density and is suitable for applications requiring lightweight structures.

5083: It has a relatively high density, but in areas such as marine engineering, the advantages of strength and corrosion resistance may outweigh its relatively high density.

• 8. Weldability

5052: It has good welding performance.

5083: It has good welding performance, but due to its high strength, you may need to pay attention to the heat-affected zone during welding.

• 9. Price

The price of 5083 aluminum plate is higher than that of 5052 aluminum plate under conventional specifications.

The choice of 5052 or 5083 depends on the specific application requirements. If strength and corrosion resistance are the primary considerations, 5083 may be a more suitable choice. If light weight and general engineering applications are the main considerations, 5052 may be more suitable.
