Product Description:5052-H34 aluminum alloy (Al-Mg series) has become the preferred material for the interior of rail transit, commercial vehicles and new energy vehicles around the world due to its high corrosion resistance, light weight and excellent formability. The 2.5mm thick and 1200mm wide design takes into account both strength and processing efficiency, and is suitable for the diversified needs of subways and long-distance buses.
Key Benefits:
| Dimension |
Technical parameters/characteristics |
Comparison with conventional materials (acrylic/steel backsheet) |
| Lightweight |
The density is 2.68g/cm³, and the weight is 1/3 of the steel plate |
Bulky steel plate (high energy consumption) and insufficient strength of plastic (easy to deform) |
| Corrosion resistance |
Salt spray ≥ 5000 hours (ISO 9227), moisture/chemical cleaners |
The steel plate needs to be galvanized (20% cost), and the plastic is prone to aging |
| Formability |
Elongation ≥12%, rollable/bent (R-angle ≥3t) |
Steel plates need to be thermoformed (high energy consumption), and plastic molds are costly |
| Eco-friendliness |
100% recyclable, 70% recycled aluminium ≥(EN 1396) |
The recycling rate of plastic < 30%, containing VOC pollutants |
