Key Properties of 5083 Aluminum Alloy
Superior Corrosion Resistance
High Mg content (4.0-4.9%) provides industry-leading seawater corrosion resistance and resists stress corrosion cracking in long-term marine exposure.
Outstanding Weldability
Compatible with MIG/TIG/FSW welding, maintaining over 90% of base material strength without requiring post-weld heat treatment.
Cryogenic Performance
Maintains toughness in extreme Arctic conditions (-196°C) without brittle fracture.
Thickness Guidelines for Marine Applications
| Application | Thickness (mm) | Recommended Temper |
| Commercial ship hull | 8-12 | H116/H321 |
| Deck plating | 5-8 | H116/O |
| LNG tank lining | 15-25 | H321 |
| Non-load superstructure | 2-5 | O/H111 |
Material Selection & Processing Notes
Temper Selection:
- H116/H321: Standard for optimized strength/corrosion resistance
- O temper: Recommended for complex cold-formed shapes
Corrosion Protection:
Combine with sacrificial anodes or epoxy coatings for enhanced protection.
Comparison with Other Marine Alloys
5052: Lower strength (suitable for interior/cost-sensitive uses)
6061: Heat-treatable but with inferior seawater resistance
