Marine aluminum alloy grades

5052 aluminum plate is an Al-Mg alloy. Magnesium is the main alloy element in the 5052 alloy aluminum plate. 5052 aluminium alloy properties have the advantages of 3 series and 5 series. It has moderate strength, especially fatigue resistance, high plasticity and corrosion resistance and cannot be strengthened by heat treatment. It is mainly used in yacht hulls.

5083 aluminum alloy has a small activation ring in seawater and is easy to return to its passivity state. At the same time, the breakdown potential and protection potential are both higher than the self-corrosion potential in the stable state, reflecting its good corrosion resistance in seawater. The rust-proof, corrosion-resistant performance and hardness of 5083 aluminum plate determine that this product is suitable for use in marine environments and corrosive environments.

Due to its excellent corrosion resistance and high strength, 5086 aluminum plates are widely used in ship hulls, decks, cabins and other parts. In the marine environment, ships need to withstand the corrosion of seawater and the impact of wind and waves. The corrosion resistance and high strength of 5086 aluminum plates can effectively ensure the safety and service life of ships.

In order to continuously improve the comprehensive performance of 5 series marine aluminum alloys, new 5 series aluminum alloys have been developed by optimizing alloy compositions, such as 5383 registered in 1995 and 5059 aluminum alloy registered in 1999.

5383 alloy has the same processing characteristics as 5083 in terms of forming, folding, shearing, and welding. It also has better corrosion resistance and higher impact strength, which makes 5383 alloy more useful in building larger and faster ships.

6082 aluminum alloy is one of the aluminium marine extrusions for boat building. It is an aluminum alloy that can be heat treated and strengthened. A6082 aluminum alloy has medium strength and good corrosion resistance, and is light in weight. It is an ideal material for manufacturing high-speed ship parts.
