5083 aluminum alloy can be regarded as representative products of 5 series marine aluminum plate. The temper are O, H111, H112, H116, H321 and so on. The composition of 5083 aluminum alloy is aluminum aluminum: balance, silicon Si: ≤0.40, copper Cu: ≤0.10 , Magnesium Mg: 4.0 to 4.9, zinc Zn: ≤0.25 Mn Mn: 0.40 to 1.0 Titanium Ti: ≤ 0.15 Cr Cr: 0.05 to 0.25 Fe Fe: 0 to 0.400, 5083 Aluminum alloy has moderate strength, good corrosion resistance and good formability , High resistance to fatigue, generally used as the main structure of the hull. Others such as 5052,5086,5454,5456, etc., are also used in hull structures or pressure vessels, pipes, hulls and decks.
