Aluminium h321 of 5083 and 5086 aluminum grades are usually applied to shipbuilding and boat building industry. The general choice of h321 aluminum for boat is mainly based on its special material properties and process characteristics, which make H321 aluminum plate have unique advantages in shipbuilding.

The aluminium h321 represents the degree of work hardening of aluminum plates after hot and cold working. Specifically, the internal structure and properties of aluminum plates in h321 temper are optimized during heat treatment and cold working, resulting in good strength and toughness. This balance of strength and toughness enables the H321 aluminum plate to withstand the various stresses and impacts encountered by the ship's hull during navigation.

In addition, aluminium H321 plates have good corrosion resistance and welding properties. In the marine environment, the hull needs to withstand salt spray, humidity and other harsh conditions of erosion, and H321 temper of the aluminum plate can effectively resist these corrosive factors, to maintain the stability and safety of the hull. At the same time, its good welding performance also makes the hull structure more solid and reliable.

5086 and 5083 h321 aluminum plate show great advantages of corrosion resistance and high strength when used in sea water environment, so they are typical marine grade aluminum plate products. Besides of H321 temper, the marine grade aluminum plate for shipbuilding also adopt other tempers, like H32, H111, H116, o and so on. Different tempers of marine grade aluminum alloy have different properties, and then have different application area, they combine together to build a whole all-aluminum boat.

In summary, aluminium h321 plate has become the preferred material in shipbuilding due to its excellent material properties and process characteristics. It can not only meet the strength and toughness requirements of the hull structure, but also maintain good corrosion resistance and welding performance in the harsh marine environment, thus ensuring the safety and stability of the ship.
