| Technical parameter | The surface of the silver-plated copper wire should be smooth and not discolored, without metal particles, burrs, any mechanical damage and other defects that damage the quality of the product. The coating is continuously and firmly attached to the surface of the copper wire, and there is no spot, black and discoloration phenomenon within 30 minutes at + (400±5) ℃ |
| According to customer requirements, the silver layer thickness of more than 1 micron silver plated copper wire should be subjected to sodium polysulfide test 1-3 cycles, no black |
