Conductive Coating Silver Plated Electrolytic Copper Powder

Spec: 1-3um, 5um or 8um, Cu%: 99.9%, copper shape has spherical, flake or dendritic, welcome to inquiry.

Application for silver plated copper powder:

1. Solder replacement

2. High Conductivity—Low Surface resistivity

3. Shielding gaskets

4. Tough and durable coating 

5. Printed circuit boards

6. Rub off resistant

7. Via fill pastes 

8. Corrosion resistant coating 

9. Suitable especially for 3-dimensional conductivity,

10. for use in carbon brush bodies, 

11. for conductive plastics or elastomers as fillers, conductive adhesives, conductive pastes ..

It was found that a fairly continuous silver layer was formed on the surface of copper powder by the electroless type of substitution plating. When the silver content reached 10 wt. %, silver was homogeneously distributed around the copper particles and few free silver particles were detected.
