Aluminium alloy 5083 plate for boat is a common seen product of 5000 series aluminum alloy in marine grade for boat building. For the structure of an aluminium boat, the hull is made of aluminum alloy, 5083 aluminum plate is used, the wharf is made of aluminum alloy buoys – 5083 aluminum plate, and the aluminum alloy checker plate are used for deck (5052 aluminum plate is used). Considering the light weight of the hull, generally thin aluminium plates should be used as much as possible, but the depth of corrosion of the aluminum plates during the service time should also be considered.
Usually, the aluminium alloy 5083 plate for boat used are thin plates above 1.6mm and thick aluminium plates above 30mm. In order to reduce welding, 2.0m wide marine grade aluminum plate is often used for large ships, 2.5m wide 5083 aluminum plate is used, and the length is generally 6m, and some special specifications are also used according to the shipyard contract. To prevent slippage, the deck adopts checker aluminium plate. 5083 aluminum alloy plate together with 5052 aluminum plate, 5086 aluminum plate, 5454 aluminum plate and 6061 aluminum plate, are regard as the typical marine grade aluminum plate product series.
Aluminium alloy 5083 plate for boat can be divided into aluminum alloys for hull structure and aluminum alloys for outfitting according to their purposes. The aluminum alloys used in the hull structure are mainly 5083, 5086 and 5456. The 6000 series alloys aluminium plate are mainly used for the superstructure of ships due to intergranular corrosion in seawater. It is an extruded profile. The 5000 series alloy aluminum plate has superior strength and process performance after heat treatment, and has a broad application prospect in shipbuilding. It is mainly used for the superstructure of ships, such as extruded structure, armor plate, etc.
