5083 aluminum sheet is a high-strength marine-grade alloy with excellent corrosion resistance and weldability. Ideal for shipbuilding, LNG tanks, and industrial applications. Reliable 5083 aluminum supplier with competitive pricing and global delivery.
Among aluminum alloys, 5083 aluminum sheet is a benchmark high-magnesium, Al-Mg series anti-rust alloy. With four core advantages-exceptional corrosion resistance, medium-to-high strength, outstanding weldability, and excellent low-temperature toughness, it has become a high-performance material for marine engineering, pressure vessels, cryogenic equipment, and heavy-duty transportation.
Combining lightweight performance with long-term reliability, 5083 aluminum plate is an ideal alternative to steel in harsh operating environments, helping reduce weight, control costs, and improve efficiency.
5083 aluminum sheet uses magnesium as its primary alloying element, with a magnesium content of 4.0%-4.9%. It offers outstanding corrosion resistance and weldability. Its machinability varies with temper: it maintains better ductility in semi-cold-worked conditions, while ductility decreases after a higher degree of cold working.
5083 aluminum alloy plate has higher strength than 5052 aluminum alloy plate and also provides excellent thermal conductivity. In the annealed temper, its excellent ductility allows it to retain good formability. It is highly suitable for welding and can be strengthened through cold working.
Due to its exceptional corrosion resistance, 5083 aluminum alloy is widely used in marine applications. In addition, it remains stable at extremely low temperatures without embrittlement or loss of performance, making it particularly suitable for cryogenic applications. Because of its high strength, 5083 aluminum alloy is also used in vehicle armor plate manufacturing.
To date, HAOMEI 5083 aluminum sheet has obtained certifications from five major classification societies:
China Classification Society (CCS)
American Bureau of Shipping (ABS)
Bureau Veritas (BV)
Lloyd's Register (LR)
Korean Register (KR)
5083-H116
Suitable for 5xxx series alloys with a magnesium content of 4% or above. Products in this temper meet specified mechanical-property requirements and provide resistance to exfoliation corrosion and general corrosion.
5083-H111
A fully annealed product that has undergone a moderate degree of strain hardening but does not reach the hardness level of H11 temper.
5083-H112
Suitable for hot-rolled products. The mechanical properties of this temper comply with relevant standard requirements.
5083-H321
Applicable to aluminum products with a magnesium content above 4%. It is strain hardened to a degree slightly lower than H32 after thermal and cold working. H116 has stricter requirements for corrosion resistance and magnesium content, while H321 offers good performance stability.

1. Exceptional Corrosion Resistance, Especially to Seawater
Because of its high magnesium content, 5083 offers excellent resistance to highly saline marine atmospheres and seawater. It effectively resists pitting corrosion and stress corrosion, making it a preferred choice for demanding marine environments.
2. Outstanding Weldability
While maintaining high strength, 5083 aluminum plate provides excellent welding compatibility. Whether using arc welding or friction stir welding, welded joints can achieve strength close to that of the base material, with stable and reliable weld quality.
3. Excellent Low-Temperature Stability
Many metals become brittle at low temperatures, but 5083 aluminum plate retains—and may even improve, its mechanical performance as temperatures decrease. In liquid-nitrogen environments at –196°C, its tensile strength and elongation can improve, making it a recognized preferred material for cryogenic pressure vessels.
4. Medium-to-High Strength and Good Formability
Among non-heat-treatable aluminum alloys, 5083 belongs to the high-strength category. It can withstand substantial mechanical loads while retaining good processing ductility.
1. Shipbuilding and Marine Engineering — Core Application
5083 aluminum plate is widely used for:
Hull outer plates
Deck structures

Fuel storage tanks
Its corrosion resistance and cryogenic performance are particularly important in these applications.
3. Rail Transit and Automotive Applications
Used in railcar structures, tank trucks, and lightweight components to achieve a balance between strength and weight reduction.
4. Defense and High-End Manufacturing
5083 aluminum plate is also used for armored vehicles and protective structures, demonstrating its high strength and impact resistance.
5. Precision Manufacturing
Suitable for mold manufacturing, fixtures, automated machinery parts, and aerospace components requiring high-precision machining.
