Silver-coated copper powder using advanced technology coating silver, abtain the niform layer of silver at the surface of copper beads. This product is a perfect combination of the high conductivity, the high shielding effectiveness of silver and the high conductivity, and the cheap of copper powder，instead of the pure silver powder is one of the best materials to achieve a very high price.
This product with high conductivity and temperature resistance up-to 180℃ is mainly used to conductive silicone rubber (plastics), conductive paint, and conductive slurry.
Granular silver coated copper powder forms silver coatings with different thicknesses on the surface of ultrafine copper powder, overcoming the defect of easy oxidation of copper powder. Spherical powder has a higher powder filling amount and can achieve a solid content of 60% -85% in the product addition ratio. It can solve the problem of deformation during the product solidification process. And it has weldability, and the welding strength can reach a tensile force of 2kg.
The dendritic silver coated copper chemical plating technology forms silver coatings of different thicknesses on the surface of ultrafine copper powder, which overcomes the defect of easy oxidation of copper powder. The dendritic silver coated copper has better oxidation resistance in the field of conductive paint and slurry, especially in salt test performance compared to flake powder. And it can play a vertical conductive role in the product, connecting the upper and lower layers for conductivity, as well as serving as a conductive skeleton
We can also customize according to customer needs containing the variety of silver content and particle size distribution of copper powder.
