Product Description

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

5083 Aluminum Alloy Overview

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 specifically designed for welding structures and offers exceptional resistance to seawater along with superior 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

Structural Benefits

40% weight reduction vs. steel flooring
Tensile strength: 275-350 MPa (H34 temper)
Fatigue resistance exceeds 10⁷ cycles at 80MPa

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)

Maintenance Advantages

30-year service life expectancy
Corrosion-resistant in humid underground environments
Minimal lifecycle maintenance requirements

5083 Aluminum Alloy Plate for metro floor applications

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
