Prime Quality EN AW 5251 Aluminum Coil 5251 Aluminium Alloy Coil
5251 aluminum coil delivers optimal balance for marine and industrial applications, combining
5052's workability with near-5083 performance at competitive pricing. Its unique property
profile makes it particularly valuable for coastal infrastructure and specialized transportation
equipment.
Key Characteristics
• Moderate Mg content (2.0-2.5%) offering balanced strength
• Exceptional corrosion resistance - outperforms 5052 in marine environments
• Excellent weldability - suitable for MIG/TIG welding
• Anodizing-friendly with good surface treatment adaptability
• Cost-performance leader between 5052 and 5083 alloys
Mechanical Properties
| Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Hardness (HB) |
| O | 180-220 | 80-120 | 18-25 | 45-55 |
| H32 | 220-260 | 160-200 | 8-12 | 65-75 |
| H34 | 240-280 | 180-220 | 6-10 | 70-80 |
Competitive Advantages
✅ Marine-Grade Corrosion Resistance
• Superior to 5052 in salt spray tests (1000+ hours)
• Excellent SCC resistance
✅ Manufacturing Flexibility
• Cold work hardening rate: 40-50% strength increase (H32 vs O)
• Minimum bend radius: 2×thickness (H32 temper)
✅ Economic Value
• 15-20% cost saving vs 5083 with comparable performance
✅ Welding Performance
• Weld efficiency: >90% (using 5356 filler)
• No post-weld heat treatment required
Industry Applications
① Transportation
• Shipbuilding: Cabin panels, auxiliary decks (1.5-4mm)
• Automotive: Truck flooring, fuel tank brackets (H34, 2.0-3.0mm)
② Architecture
• Coastal building facades (1.2-2.5mm)
• Bridge guardrails (H32, 3.0-6.0mm)
③ Industrial
• Chemical tank linings (O temper for deep drawing)
• Cryogenic equipment housings
