When it comes to marine grade aluminum plate, 5083 aluminum plates are the most familiar ones. Marine aluminum plate is a new field of research and development and application of aluminum plate products. At present, 5083 marine grade aluminum for ship building has become an important indicator to measure the comprehensive strength of aluminum sheet manufacturers. So why is the 5083 aluminum plate favored by shipbuilding companies?


5083 marine grade aluminum for ship building belongs to Al-Mg alloy with moderate strength, good corrosion resistance, good weldability and good cold workability. It is widely used in the manufacture of aircraft fuel tanks, oil pipes, transportation vehicles, ship sheet metal parts, instruments, street lamp brackets, rivets, and hardware products. , Electrical enclosures, etc. In the field of shipbuilding, 5083H116/H321/H112 aluminum plate are mostly used for shipbuilding decks, engine pedestals, ship sides, ship bottom outer plates and other parts.

5083 marine grade aluminum for ship building

The 5083 marine grade aluminum plate meets the material selection requirements for shipbuilding aluminum plates. That is the reason why 5083 aluminum plate is known as the most common use marine grade aluminum plate for ship building.


1, High specific strength and specific modulus.

The structural strength and size of a ship are closely related to the yield strength and modulus of elasticity of the material. Since the elastic modulus and density of aluminum alloy are roughly the same, the addition of alloying elements has little effect, and increasing the yield strength within a certain range is effective for reducing the ship structure. 5083 aluminum plate has medium strength, excellent corrosion resistance and weldability.

2, Excellent welding performance.

The 5083 aluminum plate has good welding crack resistance, and cracks are not easy to appear during welding.

3, Excellent corrosion resistance.

Corrosion resistance is one of the main hallmarks of marine alloys. The 5083 aluminum plate is a typical anti-rust aluminum plate, which has good corrosion resistance, can adapt to the harsh marine environment, and is durable.

4, The density is small.

The specific gravity of 5083 marine grade aluminum for ship building is small, which can reduce the weight of the ship plate, save energy consumption and increase the load.

5, Safety and environmental protection.

Aluminum alloy does not burn, is safe in case of fire, has a high recovery rate, can be recycled, and has good environmental protection.
