Boat aluminium 5083 is a member of Al-Mg series, boasting unique system among 5000 series. The alloy tempers include O, HXX and HXXX. 5083 plates of different alloys are used regularly in numerous industries, like marine building, vehicle tanks, automobile components, welded parts of plane plates, stress vessels requiring strict fire safety, refrigeration gadgets, television towers, drilling device, transportation device, armor, etc.
In boat building 5083 aluminium sheet plate serves as raw materials for the hull, running systems, decks and different components, among which the most crucial one is the underwater a part of the hull inside the perennial contact with seawater. The hull ought to be capable of resist the corrosion of seawater and be durable for a long term. The 5083H116 aluminum plate and 5083H321 aluminum plate are the most typically used on this a part of the product. Although those  forms of plates range from others best in temperature of production, they show much higher corrosion resistance and are extra suitable for the underwater environment of the ocean than H111 and H112.
First rate 5083-H112 aluminum plate is a representative made from aluminum alloy with moderate energy, corrosion resistance and welding performance. The plate is simple to form and about 20% tougher than 5052. The anti-rust aluminum plate can not be strengthened by warmness remedy. It has low energy and excessive plasticity. At present, maximum shipbuilding organisations still decide on 5083H116 and 5083H321.
