MC Aluminum produces 5083 marine-grade aluminum plates with a typical thickness range of 3–50mm, widths from 1000–3100mm, and lengths up to 1000–13000mm. These size specifications meet the manufacturing needs of various ship structures and components.
Common tempers for 5083 marine aluminum sheets include O, H32, H34, H22, H24, H116, H111, etc. The temper affects properties such as hardness, strength, and machinability. It’s essential to choose the appropriate temper based on the specific part and performance requirements in shipbuilding.
Technical Features of 5083 Marine Aluminum
1.Corrosion Resistance: As an Al-Mg alloy, with magnesium as the main element, 5083 has excellent corrosion resistance in marine environments, effectively resisting seawater corrosion and prolonging vessel lifespan.
2.Weldability: Excellent weldability compatible with multiple welding methods (e.g., TIG, MIG), ensuring strong and tight welds, improving structural integrity and sealing.
3.Strength: Medium strength that can be enhanced through work hardening. Different thicknesses offer varying strength levels, with thicker plates able to withstand higher loads.
4.Formability: Good cold-working performance, easily shaped into different forms as required by ship structure designs.

Applications of 5083 Marine Aluminum
Used in ship and offshore engineering superstructures, such as hull structures and cabins. Smaller diameter aluminum tubes are used in ship systems, while larger pipes and bars are used as masts, beams, etc. To reduce weight, thinner aluminum profiles are also used in some structural components.
Common applications include LNG storage tanks, ferries, yachts, patrol boats, and other large marine superstructures, lifting platforms, and offshore drilling platforms.
