Being a member of marine grade aluminium manufacturers in china, Haomei Aluminum engaged in 5000 series and 6000 series aluminum alloy for marine environment. Ship structures are mostly used in harsh seawater media and marine environments, so whether aluminum alloys are resistant to corrosion is one of the main indicators to determine whether they can be used as marine grade aluminum alloys. It is generally required that the marine grade aluminum alloy matrix and welded joints have no tendency to stress corrosion, exfoliation corrosion and intergranular corrosion in seawater and marine environments; contact corrosion, crevice corrosion and marine organism adhesion corrosion should be avoided as much as possible; small uniform corrosion and spot corrosion are allowed.

Experience has shown that any kind of aluminum small boat can be used for decades without suffering any noticeable corrosion. The decommissioning of such vessels is usually due to technological obsolescence rather than the ageing of aluminium structures. In general, the excellent marine weather resistance, especially seawater corrosion resistance, of the 5000 series and 6000 series aluminum-magnesium alloys has now been recognized. As marine grade aluminum supplier based in China, Haomei Aluminum offer 5052, 5083, 5083, 5383 and 6061 marine grade aluminum sheet and marine grade aluminum profile. Among them, 5083 aluminum plate is a typical aluminum alloy for welding. It has the highest strength among non-heat-treated alloys, and has good weldability, corrosion resistance and low temperature performance. It can be used as a marine aluminum plate on the side of the ship.

At present, marine grade aluminium manufacturers in china has entered the world shipbuilding market certification. Because of marine grade aluminum alloy’s low density and high strength, the side of the ship made of it can reduce the weight of the ship by more than 20%.
