UK manufacturer and supplier of quality copper terminals, busbars, earth bars, coils, heat sinks and braids to the electrical industry

Silver (Ag)


Silver retains stable surface contact resistance under most conditions and provides by far the best protective coating for electrical applications of copper. Its conductivity is the best available, slightly better than pure copper, and it has no detrimental effect on the bulk conductivity of a copper component or cable at any temperature up to melting. Copper-silver brazing provides excellent high integrity connections but tin-based solders are detrimental and counter-productive with silver coatings. Silver coating is used for high-reliability contacts and bus-bars plus instrument cables and their terminations.
