5083 H321 H116 Marine Aluminum Plate Description
5083-H321 Aluminum Plate
5083-H321 aluminum plate is well known for its excellent performance in extreme environments. 5083 marine aluminum plate belongs to 5xxx aluminum-magnesium alloy, which is a typical rust-proof aluminum plate with good corrosion resistance, excellent weldability and good cold workability. 5083 has strong corrosion resistance in seawater and industrial chemical environments.
5083-H321 aluminum plate can also maintain excellent strength after welding. It has the highest strength among non-heat-treatable alloys, but it is not recommended to use above 65°C. Its tensile strength (MPa) is greater than 305Mpa, conditional yield strength (MPa) is greater than 215MPa, elongation 10% (%) is greater than 20, and elongation (5%) is greater than 12.
5083 H116 Aluminum Plate
5083 H116 marine aluminum plate is a high-strength, corrosion-resistant aluminum-magnesium alloy plate designed for marine environments. It belongs to the 5xxx series aluminum alloy, with magnesium as the main alloying element, and has excellent seawater corrosion resistance, good weldability and strength stability. The 5083 H116 aluminum plate state means that the material has been stress-relieved and stabilized, and is specifically used for marine and ship structures that require long-term corrosion resistance and strength retention.

Feature Comparison of 5083 H321 & H116 aluminum plate
| Application Area | Description |
|---|---|
| Hull plating & keel plates | Main structural components exposed to seawater |
| Decks & bulkheads | Structural frames within ships |
| Offshore platforms & floating bridges | Marine and coastal engineering structures |
| Naval defense vessels | Armor plating and protective panels |
| Port & harbor infrastructure | Piers, seawalls, wave breakers |
| Refrigerated cargo ships & containers | Panels for cold chain and transport containers |
| Feature | 5083 H321 Marine Aluminum Plate | 5083 H116 Marine Aluminum Plate |
|---|---|---|
| Heat Treatment | Strain-hardened and thermally stabilized | Hot-rolled and thermally stabilized |
| Corrosion Resistance | Excellent, especially in warm and humid climates | Excellent, suitable for all marine environments |
| Workability | Great for bending, forming, and welding | Excellent for welding, cutting, and fabrication |
| Mechanical Stability | Very stable, good for long-term structural use | Stable, ideal for large-scale marine structures |
| Specification Standards | ASTM B928 / H321 | ASTM B928 / H116 |
