Marine aluminum alloy 5083 plate is a common product of 5000 series marine grade alloy aluminum plate, which is used in shipbuilding. Aluminum boat structure, the hull is made of aluminum alloy, 5083 aluminum plate is used, the wharf is made of aluminum alloy buoy - 5083 Aluminum Sheet, and the deck is made of aluminum alloy checker plate (5052 aluminum plate is used). Considering the light weight of the hull, the thin aluminum plate should generally be used as much as possible, but the corrosion depth of the aluminum plate during service should also be considered.


Usually, the aluminum alloy 5083 marine plate is a thin plate with a thickness of more than 1.6mm and a thick aluminum plate with a thickness of more than 30mm. In order to reduce welding, 2.0m wide marine grade aluminum plate is often used in large ships, using 2.5m wide 5083 aluminum plate, the length is generally 6m, and some special specifications are also used according to the shipyard contract. To prevent slippage, the deck adopts lattice aluminum 5083 aluminum alloy plate boat, which is regarded as a typical marine grade aluminum plate product series together with 5052 aluminum plate, 5086 aluminum plate, 5454 aluminum plate and 6061 aluminum plate.

5083 aluminum alloy plate can be divided into aluminum alloy for hull structure and aluminum alloy for outfitting according to the purpose. The aluminum alloys used in the hull structure are mainly 5083, 5086 and 5456. The 6000 series alloy aluminum plate is mainly used for the superstructure of the ship due to intergranular corrosion in seawater. It is an extruded profile. 5000 series alloy aluminum plate has superior strength and process performance after heat treatment, and has broad application prospects in shipbuilding. Mainly used for the superstructure of ships, such as extruded structures, armor plates, etc.
