5086 Marine aluminum sheet plate

5086 aluminum plate is also one of the common marine aluminum plates, with high strength and weldability, excellent corrosion resistance and good cold working performance. Compared with 5083 marine aluminum plate, 5086 marine aluminum plate is slightly inferior in strength, but has better ductility than 5083 aluminum plate. 5086 aluminum plate can be strengthened by strain hardening and cold working until the strength exceeds that of 5083 aluminum plate.

Common alloy states of 5086 marine aluminum plate include O, H111, H112, H116 and H321. It has good welding performance, especially in arc welding, and can maintain most of its mechanical strength after welding. Since heat treatment has little effect on its strength, its welding performance is more stable, which is particularly suitable for occasions requiring high corrosion resistance, good weldability and medium strength, such as weldable parts of ships and automobiles.

◆ Light weight: 5086 aluminum plate has a small specific gravity, which can significantly reduce the weight of the ship, thereby saving energy consumption and increasing load capacity.

◆ Excellent corrosion resistance: Excellent corrosion resistance in seawater environment, reducing the cost of anti-corrosion treatments such as oiling, and extending the service life of the ship.

◆ Good weldability: 5086 aluminum plate is easy to weld, especially excellent in arc welding. Most of the mechanical strength can be maintained after welding.

◆ Medium strength: Has moderate strength to meet the needs of ship structures.

◆ Good cold working properties: 5086 aluminum plate is strengthened by strain hardening or cold mechanical working, rather than by heat treatment. This makes its performance more stable during welding and processing.

5086 marine aluminum plate is often used to manufacture ship roofs and transoms due to its good weldability and ductility. It is also widely used in the manufacture of various weldable parts of ships.
