China 5083 H321 Aluminum Plate Marine Grade Manufacturer

5083 H321 marine grade  aluminum plate belongs to Al-Mg alloy, the main alloying element is magnesium, and may also contain a small amount of silicon, iron, copper and other elements.

5083 H321 marine aluminum plate is commonly used in ship decks, engine pedestals, ship sides, ship bottom outer plates and other parts. It is the preferred material for high-end ships such as cruise ships, LNG ships, and high-speed boats.

5083 aluminum plate is a typical rust-proof alloy with high yield strength and tensile strength. It can withstand various challenges and pressures when ships are sailing at sea. Its strength is sufficient to meet the requirements of ship structures.

5083 H321 Marine Grade Aluminum plate is particularly suitable for fields such as shipbuilding. The H321 is a temper that has undergone specific work hardening and stabilization treatment, which allows the aluminum plate to have a certain strength while maintaining good toughness and corrosion resistance.

H116 has good corrosion resistance, H321 has good corrosion resistance and more stable performance. It has higher hardness and better stability than H116 aluminum plate, and has good anti-corrosion performance after painting. Both can be used as marine aluminum plates.

Our 5083 H321, H116 Marine grade aluminum plates are manufactured in our advanced factories using strict quality and environmental management systems, and have passed CCS, DNV, NK, CCS, ABS, BV, LR, KR certifications.

Mechanical Property of 5083  Aluminum

5083 and 5086 marine-grade aluminum plates, which are both widely used in shipbuilding and offshore applications, primarily lie in their alloy compositions, mechanical properties, and application focuses.

Both alloys have good weldability, compatible with methods like TIG, MIG, and resistance welding, 5083 aluminum plates are used in high-strength structural parts such as ship hulls, decks, bulkheads, offshore platform frames, and pressure vessels.

Its strength-to-weight ratio makes it ideal for large vessels (e.g., cruise ships, LNG carriers) where structural integrity is critical.

5086 aluminum sheets are mostly used for for components requiring formability, such as boat hulls (smaller vessels, yachts), fuel tanks, piping systems, and decorative or curved panels.

5083 aluminum offers higher tensile and yield strengths due to its higher Mg content, making it better suited for load-bearing structural components.

5086 aluminum with lower strength but higher elongation and superior ductility and formability, which is ideal for complex-shaped parts requiring bending or shaping.
