Marine grade aluminum alloy is also called marine grade aluminum casting alloy,it is used for shipbuidling. marine aluminum alloy has better corrosion resistance and better welding and processing performance than other aluminum alloys.

Marine grade aluminum alloys are mainly 5 series and 6 series, and the use rate of the 5 series is the highest, because the 5 series aluminum alloy is a typical rustproof aluminum alloy, which is most suitable for the marine environment.Such as: 5086 marine grade aluminum, 5083 marine grade aluminum, 5052 marine grade aluminum and so on. There are also many types of marine grade aluminum alloys, such as marine grade aluminum plate, marine grade aluminum extrusions, marine grade aluminum pipe, etc.
The reason why shipbuilding materials use aluminum alloy instead of steel is because marine grade aluminum alloy has many advantages.

1. The specific gravity is small, so the weight of the marine grade aluminum plate is relatively light, and the weight of the ship is reduced, which saves fuel and improves the speed of the ship.

2. Corrosion resistance, aluminum alloy has better corrosion resistance, so the service life is longer and the cost can be reduced.

3. Aluminum alloy processing performance and welding performance are better, and waste is easy to recycle.
