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



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.
