Silver Plating

Available in Chicago, IL

Keystone Corporation is an industry leader [in the GEO area] of silver plating. Used in a variety of 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.

About Silver and it’s Effectiveness in Silver Plating

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. In microwave applications, silver plated parts can carry an extremely high current load while reducing loss at the highest microwave frequencies. 

About Our Silver Plating Process

Keystone Corporation offers engineered packaging solutions for silver plated components including the use of specific vapor corrosion inhibiting (VCI) packaging materials. All of our silver plating processes are also available for both 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 tarnish over extended storage periods.

Applications for Silver Plating

Because of its temperature resistance and many other traits, silver plating becomes a strong choice for a wide variety of applications across numerous industries. Some traditional uses of Keystone’s Silver plating include:

  • Military 
  • Aerospace
  • Communications
  • Electronics
