Silver Plated Copper Wires are composed by providing concentric silver plating over bare copper conductor. This material enhances the conductivity of copper with the bright & shiny surface of the silver. In addition, the silver coating also show excellent corrosion resistance characteristics. Silver has the highest electrical and thermal conductivity of all metals as well as the highest optical reflectivity. Silver-plated wire offers excellent high-temperature lubricity making it a preferred coating for high friction applications on surfaces exposed to temperatures up to 650◦C.
From the above excellent characteristics, this conductor is a favorable choice for wires used in nuclear, aerospace, defense, military, and many more Industrial applications. MATPLAT manufactures silver-plated copper wires complying international standard ASTM B298 & also customized wires are available on special request.
