Aluminum alloy is widely used in marine due to its excellent characteristics such as low density, light weight, high strength and corrosion resistance. In recent years, with the lightweight more and more attention, the application of aluminum alloy in the marine ship is more common. Aluminum alloy for marine use mainly has 5083 aluminum plate, 5086 aluminum plate, 5754 aluminum plate, 5052 aluminum plate, 6061 aluminum plate, 6082 aluminum plate and so on, according to the different characteristics, respectively, can be used for the deck of the ship, the engine pedestal, the side of the ship, the bottom of the ship outside the board and other parts. In addition, aluminium checker plate is also widely used.

In shipbuilding, the selection of suitable aluminum is crucial, what aluminum is best for marine use takes into account a number of factors such as strength, corrosion resistance, machinability, light weight, and so on. Here are a few types of marine grade aluminum that are particularly suitable for ships:

5083 aluminum sheet:

This is an aluminum-magnesium alloy that offers low density, high toughness, high corrosion resistance, and weldability. Its main features are high strength, good corrosion resistance, excellent weldability, good ductility, and it can adapt well to the harsh marine environment.5083 aluminum plate used in shipbuilding can not only reduce the quality of the ship, but also increase the load capacity, improve the safety and service life of the ship, as well as economic.

5086 aluminum plate:

5086 aluminum alloy is widely used in the shipbuilding field for the manufacture of hulls, decks, ship structures and marine platforms and other components.

5052 aluminum plate:

This is also a commonly used marine aluminum with good corrosion resistance, weldability and medium strength. It is commonly used to manufacture components such as superstructures and decks of ships.

6061 aluminum plate:

Although it is mainly used for cantilever and bridge type components, 6061 aluminum plate is also used in the manufacture of certain ship components due to its high bending strength and ductility.

7075 aluminum plate:

Its strength and wear resistance are very high, so it is mainly used in the manufacture of some ship anchor chain and other parts that require high wear resistance.

In addition to the above types of aluminum, there are other marine aluminum materials such as 5059, 5383 aluminum plate, etc. They have their own characteristics and can be selected according to specific needs.

In general, aluminum for marine use needs to have high strength, good corrosion resistance, machinability and lightweight and other characteristics. When selecting what aluminum is best for marine use, it is necessary to comprehensively consider the ship's use of the environment, design requirements and economy and other factors to ensure that the selected aluminum materials can meet the requirements of shipbuilding.
