Aluminium Grade For Marine Use

Aluminium grade for marine use is a special alloy material used in the manufacture of ships, with the advantages of light weight, corrosion resistance and high strength. Common aluminium grade for marine use such as 5083, 5086, 5052, 6061 and 7075 have the advantages of low density, high toughness, high corrosion resistance, good machinability, high strength, etc., and are widely used in the manufacture of hull structures, decks, engine cradles, ship bottoms and transom panels, cantilevers, bridges, and anchor chains and other key and auxiliary components. The application of these marine grade aluminum alloys not only improves the performance and safety of ships, but also promotes the lightweight development of ship manufacturing industry.

aluminium grade for marine use


Common classification of aluminium grade for marine use:

1. 5000 Series Aluminium Alloys:

Mainly including 5052, 5083, 5086, 5454 and other alloys. These aluminium alloys have excellent corrosion resistance, especially in seawater environment with good corrosion resistance. Therefore, they are commonly used in the manufacture of ship hulls, cabins, decks and other components.

2. 6000 Series Aluminium Alloy:

Mainly including 6061, 6063, 6082 and other alloys. These aluminium alloys have good strength and weldability, and are suitable for the manufacture of ship's structural components, hull wall plates, etc.

3. 7000 Series Aluminium Alloys:

Mainly including 7075 and other alloys. These aluminium alloys have very high strength and hardness, and are suitable for manufacturing high-speed ships, marine machinery parts, etc.

Each kind of aluminium grade for marine use has its unique characteristics and scope of application, and the selection of suitable alloy materials can improve the performance and safety of ships. In practical application, suitable marine grade aluminum alloys are selected according to the specific use, working environment and performance requirements of the ship to ensure the quality and reliability of the ship.
