Commonly used dnv plate aluminum marine grade alloy 5086 tempers are H116, H321, H112 and H111, 5086 marine grade aluminum plate has passed CCS China Classification Society certification and DNV Det Norske Veritas certification, ABS American Bureau of Shipping certification has been successfully used on yachts, cruise ships and other hulls. 5086 plate aluminum marine grade is used for shipbuilding is mainly determined by its unique alloy properties. It has good corrosion resistance, excellent weldability, good cold workability, and medium strength. Secondly, 5086 marine grade aluminum plate has good formability, corrosion resistance, weldability, and medium strength.

When choosing dnv plate aluminum marine grade alloy 5086, you need to know:

1, Ocean cruise ships need to withstand the erosion of seawater, so 5083 aluminum plates are needed;

2, Inland river cruise ships do not have high requirements for corrosion resistance, and plate marine grade aluminum 5086 is more suitable;

3, For recreational yachts, 5052 aluminum plates are generally more cost-effective.

4, These three marine grade aluminum alloys, whose mechanical properties, corrosion resistance and welding properties are relatively relative, are mainly used in the keel plate, curved outer plate and upper outer plate of the hull structure. Haomei Aluminum's marine grade aluminum plate has been made for a long time, with a good reputation.

For ships, the welding connection has advantages over the riveting connection, so the welding connection method has been widely used in shipbuilding, basically replacing the riveted structure. At present, the automatic argon arc welding method is mainly used in the construction of aluminum ships. The good weldability of dnv plate aluminum marine grade alloy 5086 means that the tendency of aluminum alloys to form cracks during welding is small, that is, aluminum alloys have good welding crack resistance, and the performance of welded joints does not change much after welding. Because the properties lost due to welding cannot be recovered by re-heat treatment under shipbuilding conditions, this is one of the important characteristics of marine grade aluminum alloys that are different from other structural aluminum alloys.
