5154 aluminum plate for ship bottom plate can withstand corrosion in seawater and humid environments. This allows the bottom plate to be used in harsh marine environments for extended periods of time without being easily damaged. It can also provide the structural support required for the bottom plate of the ship and increase the strength and stability of the hull. This helps improve the pressure resistance of the hull, allowing it to withstand the vibrations and pressures of sailing.
5154 aluminum plate for ship bottom plate helps reduce the overall weight of the hull and improves the ship’s carrying capacity and fuel efficiency. The lightweight properties also help improve the ship’s maneuverability and navigation performance. Various geometric shapes and size requirements of ship bottom plates can also be met. It can perform bending, cutting, welding, drilling and other processing processes to facilitate installation and adjustment during ship manufacturing.
