About the Effectiveness of Silver Plating

Silver has the highest thermal conductivity, electrical conductivity and optical reflectivity in the visible portion of the electromagnetic spectrum of all metals. Silver has outstanding temperature resistance with a melting point of 962° C (1763° F). 

Silver is also a soft, ductile metal with good embeddability that performs well under high torque and loads. The unique combination of lubricity, high-temperature resistance and thermal conductivity make it ideal for high-temperature fastening or bearing applications, protecting parts in low oxygen environments and preventing the galling of nuts, fasteners, gears and bearing surfaces at high temperatures. Silver-plated parts can carry a high current load in microwave applications while reducing loss at the highest microwave frequencies. 

More About Our Silver Plating Process

Keystone Corporation offers engineered packaging solutions for silver-plated components, including specific vapor corrosion inhibiting (VCI) packaging materials. Our silver plating processes are also available for Rack and Barrel plating applications.

Additionally, supplemental anti-tarnish treatments are available for silver-plated parts, which can slow tarnishing by sealing the surface from exposure to air and water. This type of packaging eliminates the chance of silver tarnishing over extended storage periods.
