ASTM B209 AA5454 Mirror-finished Aluminum Plate Whosaler Used For Liquid Tankers
5454 mirror sheets offer a balanced combination of lightness, corrosion resistance, and hygiene,
making them ideal for food/chemical tankers. For detailed parameters (e.g., fatigue life, welding
specs), provide specific operational requirements!
Key Characteristics
♦ Alloy Type: Al-Mg alloy (5xxx series) with 2.4-3.0% Mg and 0.5-1.0% Mn, offering excellent corrosion
resistance and medium-high strength.
♦ Mirror Finish: Achieved via mechanical/electropolishing, enhancing aesthetics and cleanability.
♦ Weldability: Compatible with MIG/TIG; post-weld heat treatment unnecessary
♦ Chemical Resistance: Resists saltwater, weak acids/alkalis, ideal for food-grade (e.g., milk) and
chemical liquids
Core Advantages
✔ Lightweight: 35% lighter than stainless steel (density: 2.68 g/cm³), reducing fuel consumption.
✔ Stress Corrosion Resistance: Optimized Mg content avoids SCC risks seen in high-Mg alloys (e.g., 5083).
✔ Cryogenic Performance: Maintains properties at -196°C, suitable for LNG tanks.
✔ Hygienic Surface: Mirror finish minimizes residue buildup, compliant with FDA/EHEDG standards.
Recommended Tempers
H32/H34: Partially hardened, balances strength (UTS≥250 MPa) and formability.
O Temper: Annealed, optimal for deep drawing (e.g., tank heads).
Comparison with Other Alloys for Tankers
| Property | 5454 | 5083 | 6061 |
| Strength | Medium (H32: 250-300 MPa) | High (H321: 270-350 MPa) | Medium (T6: 310 MPa) |
| Corrosion Resistance | Excellent (especially vs. chlorides) | Excellent (marine-grade) | Good (requires anodizing) |
| Weldability | Excellent | Excellent | Good (PWHT needed) |
| Cost | Moderate | Moderate | Low |
| Typical Use | Food/chemical tankers | Ships/pressure vessels | Truck frames |
Why 5454 Over Others?
Vs 5052: Higher strength for pressurized tanks.
Vs 5083: More cost-effective for non-extreme conditions.
Vs 6061: Superior corrosion resistance in wet environments.
Tanker Truck Applications
• Tank Body: 5454-H32 mirror sheet (3-6mm thickness), welded without coating.
• Interior: Mirror polish reduces liquid retention, meeting sanitary standards .
• End-Use: Food transport (dairy, edible oils), mild chemicals (pH-neutral).
