High Strength 5000 Series 5083 Aluminum Marine Plate Aluminium 5083 Sheet
5083 aluminum sheet belongs to Al-Mg series alloy. It is the highest strength corrosion-resistant
alloy among practical non-heat-treated alloys. And it is suitable for welding structures. Also, it is
worth mentioning that 5083 aluminum sheet has good resistance to seawater and low-temperature characteristics.
Key Properties of 5083 Aluminum Alloy
5083 aluminum alloy is a non-heat-treatable Al-Mg series alloy with exceptional marine-grade
characteristics:
♦ High Strength & Toughness
Tensile strength: 275-350 MPa (varies by temper, e.g., H116/H321)
Yield strength: ≥125 MPa (O temper) to ≥215 MPa (H116)
Excellent impact/fatigue resistance for dynamic loads (e.g., wave impacts)
♦ Superior Corrosion Resistance
High Mg content (4.0-4.9%) provides industry-leading seawater corrosion resistance
Resists stress corrosion cracking (SCC) in long-term marine exposure
♦ Outstanding Weldability
Compatible with MIG/TIG/FSW (friction stir welding)
As-welded joint strength retains >90% of base material
No post-weld heat treatment required
♦ Lightweight Advantage
Density: 2.66 g/cm³ (~65% lighter than steel) reduces vessel fuel consumption
♦ Cryogenic Performance
Maintains toughness in Arctic conditions (-196°C) without brittle fracture
Thickness Guidelines for Marine Plate
| Application | Thickness (mm) | Recommended Temper |
| Small yacht hull | 4-6 | H116/H321 |
| 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: For complex cold-formed shapes
Corrosion Protection:
Combine with sacrificial anodes or epoxy coatings
Welding:
Use 5356/5183 filler wires for best performance
Comparison with Other Marine Alloys
5052: Lower strength (interior/cost-sensitive uses)
6061: Heat-treatable but inferior seawater resistance
5083 dominates marine engineering due to its unmatched balance of corrosion resistance, strength,
and weldability, making it ideal for safety-critical maritime structures.
