DNV (Det Norske Veritas) certified marine aluminum plate 5083 is a high-strength aluminum alloy widely used in shipbuilding and marine engineering. As a high-magnesium alloy, 5083 aluminum alloy offers excellent corrosion resistance, good weldability and high strength, making it ideal for use in marine environments.

Properties of marine aluminum plate 5083:

- Corrosion Resistance:

As a typical rust-resistant aluminum, 5083 aluminum plate is particularly resistant to seawater corrosion and exhibits excellent corrosion resistance in marine environments. Its H116/H321 temper 5083 marine aluminum plate performs exceptionally well in salt spray testing, with a corrosion lifespan 30% longer than that of ordinary aluminum alloys. It effectively resists erosion from seawater, marine atmosphere and biofouling.

- Weldability:

Excellent weldability allows for standard welding methods such as MIG and TIG welding with minimal post-weld strength loss. We recommend using 5356 or 5183 welding wire, and the surface must be cleaned before welding.

- Mechanical Properties:

Taking H116 as an example, its tensile strength is ≥270 MPa, yield strength is ≥125 MPa, elongation is ≥10% (gauge length 50 mm), and hardness is approximately 75 HB, demonstrating excellent strength and toughness.

Common Tempers of DNV certified marine aluminum plate 5083:

- H116:

It lies between H112 and H321, offering improved corrosion resistance and strength. It is commonly used in ship decks and sides.

- H321:

Its tensile strength is 305-385 MPa, yield strength is 215-295 MPa, and elongation is ≥12%, demonstrating high strength and good fatigue resistance.

- O:

This is the annealed condition. The 5083 o aluminum plate is soft and tough, making it easy to form and weld.

Specifications of marine aluminum plate 5083:

- Thickness:

Common thicknesses range from 3 to 50 mm. The thickness range varies between manufacturers, with some manufacturers capable of producing thicker or thinner plates.

- Width:

Typical widths are 2000mm or wider, and can be customized according to customer needs.

- Length:

6000mm, 8000mm, 9000mm, and 12000mm are common, and customization is also possible.

The Significance of DNV Certification

DNV certification is conducted by DNV - Det Norske Veritas, a leading global provider of certification and risk management services. Founded in 1864, DNV certification is recognized by over 80 countries worldwide and holds high authority and influence. DNV certification covers chemical composition, mechanical properties, processability (such as bending and welding), and factory production process audits, ensuring that the plate meets relevant shipbuilding standards.
