5086 and 5083 aluminium sheet plate marine grade belongs to the 5000 collection aluminum-magnesium alloy. Due to its brilliant anti-corrosion and anti-rust feature, it is a consultant manufactured from aluminum alloy anti-rust aluminum plate.According to the distinction within the content material of magnesium alloys, the products of 5000 series aluminum alloys are: 5005, 5052, 5754, 5056, 5086, 5083 and so on. 5083 aluminum sheet and 5086 aluminum plate are the representatives of outstanding anti-rust aluminum plates. The content material of 5086 marine grade aluminum plate is silicon Si≤zero.40 and copper Cu≤0.10. Take 5086 rust-evidence aluminum plate for example. It's miles specially used in occasions that require excessive corrosion resistance, desirable weldability and medium strength, consisting of motors and airplanes. Welding parts, ship board production and ship add-ons, etc.Generally talking, the state of generally used 5086 aluminium sheet plate marine grade is O, H111, H112, H116, H321, and so on. In terms of mechanical houses, 5086 anti-rust aluminum plate has a tensile power σb(MPa): ≥240, and a conditional yield power σ0. 2(MPa): ≥ninety five, elongation δ10(%): ≥10, elongation δfive(%): ≥12, anti-rust aluminum alloy represented with the aid of 5083 and 5086 aluminum plates, in the modern marine market along with marine grade aluminum plates China has big improvement potential. At present, many domestic aluminum sheet processing firms also are increasing this research and development efforts to broaden the shipbuilding market for rust-evidence aluminum sheets.
