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
| 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
• Beijing Subway Line 17 rolling stock
• Shanghai Metro Line 14 trainsets
• Singapore Circle Line MRT vehicles
Company Advantages
1) Full sets of imported vertical intelligent storage and logistic management system, and finishing
lines which fulfill all the requirements on various kinds of Aluminium plate,sheet and strip products.
2) We have has built up on the basis of outstanding management and complete quality control system
under its rich experiences and has got many kinds of quality management certificates such as ISO90
-01:2015, ISO14001:2015,ISO45001:2018,IATF16949:2016,AS9100D,ISO/TS22163:2017, and has
passed ABS,CCS, DNVGL,LR,NK,KR etc.proof from National Classification Society.
3) We take social responsibility and regards environment protection as main task for long-term develop
-ment. It is featured with pulse-type bag dedust system from NEDERMAN Germany,which emission
index of main exhaust stuff and particles are lower than national criteria.
