GNEE Aluminum, a trusted aluminum supplier in China, offers high-quality 5083-H32 aluminum plates, a non-heat-treatable alloy from the 5000 series known for its exceptional corrosion resistance, medium-to-high strength, and excellent performance in harsh environments.
The H32 temper indicates that the material has undergone strain hardening and partial annealing to achieve a quarter-hard condition, providing a balanced combination of strength and formability-ideal for applications requiring both durability and ease of fabrication.
Overview of 5083-H32 Aluminum Plate
5083-H32 aluminum plate combines the superior corrosion resistance of marine-grade alloys with excellent mechanical properties, making it a preferred choice in the shipbuilding, transportation, and chemical processing industries.
Its ability to maintain strength and structural stability in seawater and low-temperature environments ensures long-term performance for both commercial and military vessels.
Classification and Certification
To ensure quality and compliance in marine applications, GNEE Aluminum supplies 5083-H32 aluminum plates certified by leading international classification societies, including :
CCS – China Classification Society
ABS – American Bureau of Shipping
DNV – Det Norske Veritas
BV – Bureau Veritas (France)
LR – Lloyd's Register (United Kingdom)
These certifications confirm that GNEE's 5083-H32 aluminum plates meet international maritime standards for shipbuilding and offshore engineering.
Alloy Composition (Typical)
5083 aluminum belongs to the Al-Mg system, with magnesium as the principal alloying element and minor additions of manganese and chromium for enhanced strength and corrosion resistance.
| Element | Content (%) |
|---|---|
| Magnesium (Mg) | 4.0 – 4.9 |
| Manganese (Mn) | 0.4 – 1.0 |
| Chromium (Cr) | 0.05 – 0.25 |
| Silicon (Si), Iron (Fe), Copper (Cu), Zinc (Zn), Titanium (Ti) | ≤ 0.4 each |
| Aluminum (Al) | Balance |
This composition gives 5083 excellent resistance to seawater corrosion and outstanding strength retention after welding.
Temper Definition – H32
The H32 temper means the aluminum plate has been strain-hardened and then stabilized by annealing, achieving a strength level between the fully annealed (O) and fully hardened tempers.
H3: Strain-hardened and stabilized.
2: Indicates approximately ¼-hard strength.
This temper offers good formability while maintaining sufficient strength for structural use in marine and industrial environments.
Key Features of GNEE 5083-H32 Aluminum Plate
Excellent Corrosion Resistance:
Superior resistance to seawater, industrial chemicals, and atmospheric corrosion-ideal for humid and saline environments without additional coatings.
Outstanding Weldability:
Welded joints can achieve 90%–95% of the base metal's strength, making it highly suitable for complex welded ship structures.
High Strength and Stability:
Delivers reliable strength and dimensional stability under load, essential for hulls, decks, and pressure vessels.
Excellent Low-Temperature Performance:
Maintains ductility and toughness at sub-zero temperatures, making it suitable for LNG tanks, cryogenic storage, and polar engineering.
Non-Heat-Treatable Alloy:
Strength is obtained through cold working, maintaining uniform mechanical properties without thermal distortion.
Temperature Limitation:
Recommended for service temperatures below 65°C (150°F) to avoid sensitization of magnesium phases.
Good Formability:
Allows cold bending, cutting, and forming while retaining structural integrity-though less ductile than the fully annealed O temper.
Applications of 5083-H32 Aluminum Plate
Shipbuilding: Hulls, decks, bulkheads, and superstructures
Marine Engineering: Offshore platforms, gangways, and ship components
Transportation: Automotive and rail body panels, truck trailers
Cryogenic Equipment: LNG/LPG storage and transport systems
Chemical Industry: Pressure vessels and storage tanks for corrosive media
