Al-Mg Alloy Thick 5083 Aluminum Alloy Plate For Metro Floor

Al-Mg Alloy Thick 5083 Aluminum Alloy Plate for Metro Floor

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.

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)

Recommended Material Tempers

• H32/H34: Primary choice for optimal strength-formability balance

• H111: For components requiring additional forming

• H116: Critical for corrosion-resistant applications

Special note: H34 temper provides 15% higher yield strength than H32

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

Current Applications

• Beijing Subway Line 17 rolling stock

• Shanghai Metro Line 14 trainsets

• Singapore Circle Line MRT vehicles

Company Advantages
