5000 Series Aluminum Plate 5083 H111 H116 H321 For Metro Flooring
5083 aluminum sheet belongs to the Al-Mg series alloy family and represents the highest strength corrosion-resistant alloy among practical non-heat-treated alloys. This material is particularly suitable for welding structures and offers exceptional resistance to seawater along with excellent low-temperature characteristics.
5083 aluminum (preferred tempers H116/H321) is the material of choice for metro flooring due to its lightweight properties, high strength, and lifecycle economy.
- 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 (articulated sections) |
- 40% weight reduction compared to steel flooring
- Tensile strength: 275-350 MPa (H34 temper)
- Fatigue resistance exceeds 10⁷ cycles at 80MPa
- Non-sparking characteristics (essential for underground transport)
- Fire performance meets DIN 5510-2 Class S4/SR2
- Excellent impact energy absorption (50J at -20°C)
- 30-year service life expectancy
- Corrosion-resistant in humid underground environments
- Minimal lifecycle maintenance requirements
| 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 |
5083-H111 one-piece curved flooring (60% fewer seams)
5083-H116 flooring (3.0 mm), 1.8-ton weight reduction per train
Surface: Anodized + anti-slip granules (friction coefficient ≥0.8)
5083-H321 honeycomb sandwich panels (1.5 mm face + 15 mm core)
- Anti-slip treatment (electrolytic polishing/ceramic coating)
- Electrical insulation (to prevent galvanic corrosion)
- Compliance with EN 45545-2/BS 6853 fire standards
