5000 Series Corrosion Resistance AA5083 Aluminum Alloy For Metro Flooring
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.
5083 aluminum (H116/H321 preferred) is the material of choice for metro flooring due to its lightweight,
high strength, and lifecycle economy.
Standard Thickness Specifications
♦ Standard flooring: 3-5mm (lightweight structural requirements)
♦ High-load areas: 5-8mm (doorways/passenger concentration zones)
♦ Special reinforcement: 8-12mm (under seating/equipment mounting points)
| Temper | Processing | Mechanical Properties | Applications |
| H111 | Hot-rolled + annealed | Tensile ≥270 MPa, Elong. ≥12% | Complex-shaped floor components |
| H112 | Hot-rolled + natural aging | Tensile ≥275 MPa, Yield ≥125 MPa | Standard flat panels (cost-effective) |
| H116 | Special stabilization | Tensile ≥290 MPa, Yield ≥215 MPa | High-traffic areas (wear-resistant) |
| H321 | TMCP treatment | Tensile ≥310 MPa, Yield ≥230 MPa | High-strength zones (e.g., articulated sections) |
Performance Advantages
1) Structural Benefits
✓ 40% weight reduction vs. steel flooring
✓ Tensile strength: 275-350 MPa (H34 temper)
✓ Fatigue resistance exceeds 10⁷ cycles at 80MPa
2) Safety Features
• Non-sparking characteristics (essential for underground transport)
• Fire performance meets DIN 5510-2 Class S4/SR2
• Excellent impact energy absorption (50J at -20°C)
3) Maintenance Advantages
▶ 30-year service life expectancy
▶ Corrosion-resistant in humid underground environments
▶ Minimal lifecycle maintenance requirements
Comparison with Alternative Alloys
| Alloy | Pros | Cons | Typical Uses |
| 5083 | Best corrosion resistance, weldable | Not heat-treatable | Tankers, ships, chemical tanks |
| 6061-T6 | Higher strength (310 MPa) | Poor corrosion resistance, requires pre-heat welding | Structural frames, non-corrosive parts |
| 5052 | Lower cost, excellent formability | Lower strength (210 MPa) | Lightweight covers, interior panels |
Current Applications
• Berlin U5 Line (Germany)
5083-H111 one-piece curved flooring (60% fewer seams)
• Shanghai Metro Line 14 trainsets
5083-H116 flooring (3.0 mm), 1.8-ton weight reduction per train
Surface: Anodized + anti-slip granules (friction coefficient ≥0.8)
• Singapore Circle Line MRT vehicles
5083-H321 honeycomb sandwich panels (1.5 mm face + 15 mm core)
Key design considerations:
✅ Anti-slip treatment (e.g., electrolytic polishing/ceramic coating)
✅ Electrical insulation (to prevent galvanic corrosion)
✅ Compliance with EN 45545-2/BS 6853 fire standards
Company Advantages
