Marine aluminum sheet manufacturers produce 5000 series alloy such as 5052, 5083 and 5086 for boat building. Marine grade aluminum sheets are very hard, will not break easily, and have strong corrosion resistance. Therefore, using it to make ship, boat and yachts will have a longer life. But with so many types of aluminum plates, which is more suitable for marine application?

General marine grade aluminum alloy refers to the 5000 series magnesium aluminum alloy. Distinguish models based on magnesium content, such as 5052, 5083, 5086 etc. It can be simply understood that 5052 marine grade aluminum contains less magnesium and has better formability, which makes it easier to press, while 5083 marine aluminum plate has a higher magnesium content and is brittle and hard, which is not suitable for pressing, but 5083 aluminum is harder than 5052 aluminum and has better corrosion resistance. If used in inland freshwater waters, use 5052 aluminum; if used in seawater or highly corrosive waters, use 5083 marine grade aluminum. In order to adapt to the seawater environment and beautiful, many aluminum alloy boats will use 5083 aluminum sheet as the lower part (underwater part) of the boat and 5052 aluminum sheet as the boat upper part (the water surface part).

Pay attention to the choice of marine aluminum sheet manufacturers materials:

1, Marine grade 5052 aluminum alloys are also used for outfitting, and the varieties include plates, tubes and rods.

2, Marine grade aluminium 5083 alloy can produce wide and thin extruded profiles.

3, The thickness of the board is determined by the hull structure, ship specifications and service parts. From the perspective of hull weight reduction, thin marine aluminum sheets are generally used as much as possible, but the corrosion depth of aluminum sheet during service should also be considered. Generally, the marine grade aluminum sheet for boat used are above 1. 6 mm, and marine grade aluminum plates thickness is above 30 mm. In order to reduce welding, aluminum plates with a width of 2, 5 m are usually used, and marine aluminum plates with a length of 6 m are usually used for large ships. In order to prevent slip, the deck adopts a diamond marine grade aluminum checker plate.
