Marine grade 5083 H321 Aluminum Plate LR BV ABS DNV class approved for Shipbuilding
85083 Marine Grade Aluminum. 5083 Plate,The commonly used temper of 5083 aluminum sheet is H321, with a thickness of 3-200mm and a width of 1500-2600mm. It is widely used for ship engine bases, ship decks, ship sides, bottom outer plates, etc., covering the hulls of yachts and cruise ships, etc
5083-H321 aluminum is 5083 aluminum in the H321 temper. To achieve this temper, the metal is strain hardened, and then stabilized, to a strength that is roughly a quarter of the way between annealed (O) and full-hard (H38).
5083 Aluminum plate has good corrosion resistance, the corrosion rate in seawater is very slow, the uniform corrosion rate is generally 0.025-0.05mm/ years, can resist the corrosion of seawater and marine atmosphere on the ship, reduce oil and maintenance cost, long service life.
5083 marine Aluminum Alloy plate with high strength and low fracture toughness, it is suitable for hull structure material, low fracture toughness of ideal structural material, has an important significance for ship safety.
Aluminium 5083 is known for exceptional performance in extreme environments. 5083 is highly resistant to attack by both seawater and industrial chemical environments.
Alloy 5083 also retains exceptional strength after welding. It has the highest strength of the non-heat treatable alloys but is not recommended for use in temperatures in excess of 65°C.
