Industrial SILVER PLATING with Keystone Corporation

Available Across the United States

Keystone Corporation’s silver plating has been used in countless communications, electronics, power transmission, and industrial applications. Silver plating provides excellent solderability and brazing characteristics for joining applications and has the highest electrical conductivity, heat conductivity and the lowest contact resistance of any metal, making it ideal for the electronics industry. It is often chosen as a less expensive alternative to gold for electrical connections.

Supplemental anti-tarnish treatments are available for silver-plated parts which can slow tarnishing by sealing the surface from exposure to air and water. Keystone Corporation offers engineered packaging solutions for silver-plated components, including specific vapor corrosion inhibiting (VCI) packaging materials. This type of packaging eliminates the chance of silver tarnishing over extended storage periods.

Keystone’s silver plating processes are available for both Rack and Barrel plating applications.

Due to its various traits, it has various uses and applications. Some traditional uses of Keystone’s silver plating include:

  • Military 
  • Aerospace
  • Communications
  • Electronics

Of all metals, silver has the highest thermal conductivity, electrical conductivity, and optical reflectivity in the visible portion of the electromagnetic spectrum. Silver has outstanding temperature resistance with a melting point of 962° C (1763° F). Additionally, silver is a soft, ductile metal with good embeddability that performs well under high torque and loads.

Silver’s 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.
