5083 marine grade structural aluminum have been used in the shipbuilding industry for nearly 100 years. With the rapid development of the domestic and foreign shipbuilding industries, the weight of ships has been paid more and more attention. Due to the low density, high strength, high rigidity and corrosion resistance of aluminum, ship design Compared with ships built with steel or other synthetic materials, the weight of ships built with 5083 marine grade structural aluminium is reduced by 15-20%. The high toughness, corrosion resistance and weldability of aluminum alloys provide a good choice for the construction of ship types with strict weight requirements. Due to the lower processing cost of aluminum, it is more economical to use aluminum materials to make ships. Aluminum alloy can be used as a plate, and can also be extruded and cast. Coupled with the outstanding physical properties of aluminum alloys, it is very economical to manufacture ships from aluminum alloys. From the perspective of the ship designer, ships made of aluminum alloy can achieve higher speed and longer service life. These advantages of aluminum alloy have made it develop rapidly in the application of ships. The shipbuilding industry is aluminum Provides a broad application market.



The 5083 marine grade structural aluminum used in ships can be divided into deformed aluminum alloys and cast aluminum alloys. The application of deformed aluminum alloys in shipbuilding in various countries ranges from superstructures of large surface ships to thousands of tons of all-aluminum marine research ships, ocean-going commercial ships and passenger ships. During construction, deformed aluminum alloys have been widely used in various high-speed passenger ships and military speed boats such as hydrofoils, hovercrafts, passenger ferries, catamarans, traffic boats, and landing craft. Cast 5083 marine grade aluminium
 is mainly used for pumps, pistons, outfitting parts and rainwater mine shells.
