Silver plating offers several advantages as a finish. It is one of the best electrical conductors and is easily soldered, although that capability of silver plating decreases with age. Silver plating also has excellent lubricity and smear characteristics for anti-galling fuses on static seals, bushings, etc. The color ranges of silver plating from white matte to very bright in appearance, but it will tarnish easily. Silver plating offers good corrosion resistance, depending on the base metal. Hardness varies from about 90 Brinnell to about 135 Brinnell, based on the process and plating conditions.
