5083 aluminum profiles are suitable for ships
Marine aluminum profiles are a lightweight, high-strength, corrosion-resistant, and easy-to-process material with excellent physical and mechanical properties. They are widely used in shipbuilding and ship equipment manufacturing. According to different requirements of use, classification society aluminum profiles can be divided into right-angle profiles, T-profiles, angle beam profiles, modern ship profiles and other types.
5083 aluminum profiles belong to Al-Mg alloys, with excellent corrosion resistance, high strength, good weldability and cold workability. They can meet the needs of various structural parts in shipbuilding, such as hulls, superstructures, decks and bulkheads, and are a popular choice in the shipbuilding industry.
