Product Advantages
core advantages:
| Dimension |
Technical parameters/characteristics |
Contrast copper windings |
| Electrical conductivity |
The conductivity ≥ 62% IACS (International Annealed Copper Standard), and the resistivity is 2.65μΩ·cm |
Copper is 100% IACS, but aluminum can be replaced by an increase in cross-sectional area |
| Corrosion resistance |
Dense oxide film on the surface, resistant to damp heat and sulfide corrosion (IEC 60076) |
Copper needs to be tin plated to prevent oxidation, which increases the complexity of the process |
| Eco-friendliness |
100% recyclable with a carbon footprint of 1/5 of copper (1.5kg CO2/kg) |
High carbon emissions from copper smelting (8-10kg CO2/kg) |
| Cost-effective |
The unit price is 1/3 of copper, and the comprehensive cost is reduced by 40% |
Copper prices fluctuate greatly and resources are scarce |
