Product Advantages
core advantages:
| Dimension |
Technical parameters/characteristics |
| Efficient heat dissipation |
The design of the three-dimensional wave fin increases the heat dissipation area by 50% and improves the heat exchange efficiency by 25-30%. |
| Corrosion-resistant and long-lasting |
Manganese element enhances the oxidation film, resistant to salt spray and acid rain (pH 5-9), with a lifespan of up to 15 years (traditional aluminum materials 8-10 years). |
| Precision molding |
Adapt to ultra-thin fins (thickness 0.1mm, spacing 1.8mm), stamping yield ≥99.5%. |
| Cost-effectiveness |
The material cost is 65% lower than copper, and the processing energy consumption has been reduced by 30% (with stamping speed increased to 600 times per minute). |
| Green low-carbon |
Recycled aluminum accounts for ≥50%, and its full life cycle carbon footprint is 85% lower than that of copper, complying with the EU ErP Directive. |
