Marine Grade Aluminum For Ship Building

0 Comment

Marine grade aluminum for ship building are widely used in boats and ships making due to their excellent properties such as low density, light weight, high strength and corrosion resistance. In recent years, as the weight of ships has become more and more important, the application of marine grade aluminum alloys like 5083, 5086, 5754, 5383 on ships has become more common.


Marine grade aluminum for ship building mainly include 5059 aluminum plate, 5083 aluminum plate, 5086 aluminum plate, 5383 aluminum plate, 5754 aluminum plate, 5052 aluminum plate, 6061 aluminum plate, 6063 aluminum plate, 6082 aluminum plate, etc. According to different characteristics, marine grade aluminum plate can be used for ship deck, engine pedestal, ship side, bottom outer plate and other components. In addition, marine grade aluminum checker are also widely used on deck, stairs, ramps and flooring on the ship.

The reason why marine grade aluminum alloy is widely used in shipbuilding industry is inseparable from its own advantages. Marine grade aluminum alloy has five advantages when applied to ships:

1, Aluminum alloy has low density.

Aluminum has a lower density, only one-third of steel, and is lighter than other materials, which can reduce the weight of ships and increase the speed of ships, in addition to reducing energy consumption and increasing transportation capacity.

2, Corrosion resistance.

The aluminum alloy in marine grade surface naturally forms a dense aluminum oxide film, which is not easy to rust and corrode, has a long service life, and can reduce maintenance.

3, Good workability.

Aluminum alloys have good formability and are easy to process in various forms such as cutting, stamping, cold bending, forming and cutting, and are suitable for streamlined hulls.

4, Does not burn.

Aluminum alloy marine grade does not burn, has good low temperature workability and high safety.

5, Aluminum scrap is easy to recycle.

Aluminum alloy plate and profile can be recycled.

On the whole, aluminum alloy ships have higher speed, longer service life and higher safety. Based on these advantages, the application of marine grade aluminum 5083 and other marine aluminum alloys in ships has developed rapidly. At the same time, the shipbuilding industry has also provided a broad application market for aluminum materials.


Marine grade aluminum for ship building production capacity is an important indicator to measure the strength of each aluminum plate manufacturer. At present, there are many aluminum plate manufacturers on the market. When users choose, they should choose a large aluminum processing manufacturer, compare the strength and scale of the manufacturer, and also see whether the marine grade aluminum plate has the corresponding classification society certification of CCS, DNV, BV and so on.
