5083 aluminum sheet plate for ships
5083 aluminum plate is highly suitable for ship construction due to its excellent corrosion resistance, making it capable of withstanding erosion from seawater. The 5083 marine-grade aluminum plate exhibits high corrosion resistance and effective anti-rust properties, enabling it to withstand corrosion caused by marine environments, including sea water and harsh weather conditions. This corrosion resistance significantly reduces maintenance costs associated with activities such as oiling, thereby enhancing the safety and lifespan of ships. Mainly used for decks, engine bases, ship sides, outer bottom plates, keels, and hull structural materials, 5083 marine aluminum plates are essential components for shipbuilding projects.
5083 H116 and H321 aluminum plates find extensive use in ship construction for decks, sides, bottom shells, engine bases, and keels. These plates are required to exhibit corrosion resistance, wear resistance, high strength, and hardness. Among them, the 5083 H116 and H321 aluminum plates offer superior corrosion resistance, making them more suitable for marine underwater environments compared to the H111 and H112 states.
