Alu 5083

Why Choose Marine Grade Aluminum 5083

Among the hull materials of speedboats, aluminum plates have sufficient strength and rigidity, while being able to reduce weight, resist seawater corrosion, and have good weldability. Marine grade aluminium 5083 for ship building can effectively reduce ship weight and increase ship speed.

With 5083 aluminum sheet replacing traditional steel ship, each ship can save about 8-100 tons of weight on average. Its application is not only limited to the hull and parts, but also includes furniture, cabinets and deck.

5083 aluminum plate has good anti-rust function and can adapt to the corrosion of marine climate. It is often used in some humid and marine environments. For boat building, there are mainly O, H111, H112, H116 and H321 tempers,especially 5083-H321 aluminum sheet.

Different tempers of 5083 Marine Ggrade Aluminum Plate

5083-h116 and 5083-H321 aluminum plates have better corrosion resistance and are more suitable for the underwater environment of the ocean than H111 and H112 temper. Although the temperature of 5083H116 and H321 aluminum sheets are slightly different in the production process, the corrosion resistance is significantly better than other tempers.

Applications of 5083 Aluminum Plate

5083 marine aluminum plate is a typical Al-Mg-Si alloy with high corrosion and rust resistance. The underwater part of the hull, especially in the sea water, must be able to resist the corrosion of seawater. The most commonly used ones are 5083-H116 and 5083-H321 aluminum sheets.
The keel is a longitudinal member connecting the bow post and the stern post in the center of the base of the hull. 5083 aluminum sheet is the common choice.
5083 aluminum plate is mainly used in the deck, engine pedestal, side of the ship, and the outer plate of the bottom of the ship.
5083-H116 aluminum sheet is also used in transportation field, such as automobile and aircraft fuel tank, etc.

Advantages of Aluminum 5083 for Ship Building

1. 5083 aluminum plate is of low density, contributing to the light weight of the ships and less fuel consumption. It can also improve the the length-to-width ratio of the ship and stability,which makes the ship easier to maneuver.

2. 5083 aluminum plate is of extremely good corrosion resistance, reducing maintenance costs such as oiling.

3. It has good processing and forming performance, which is easy to be processed in various forms such as cutting, stamping, cold bending, forming and cutting. This is helpful for the light weight and reasonable structure of the ships.

4. 5083 aluminum sheet is of good welding performance, reducing numbers of welds.
