5383 aluminum plate for shipbuilding is of high strength, corrosion resistance, plasticity and excellent welding performance. It has been used in large quantities as lightweight materials to make yacht shells, hull superstructures, masts, and port infrastructure.

5383 aluminum alloy is widely used in high-speed ships, such as hydrofoils, hovercraft, speedboats, cruise ships, sailboats, catamarans, and marine cruise ships, and the application parts include ship sides, bottom shells, engine pedestals, decks, roof and side panels of vessels, etc.

Since Zr is added to the 5383 alloy composition, Zr can combine with Al to form an Al3Zr phase, which can significantly improve the strength and recrystallization temperature of the 5383 aluminum alloy. Therefore, compared with 5083 aluminum alloy, 5383 aluminum alloy has higher strength and better welding performance.
