Silver plating is another electrodeposit process for electrical engineering, electronic and decorative applications. Our silver plating thickness is a minimum of 500 micro inches unless specified. Matte, Semi-bright and bright finishes are available as well as a chromate tarnish resisting treatment. Unlike gold plating, silver plating tends to oxidize much easier. For less rigorous electronics applications, silver plating is often used as a less expensive alternative to gold plating.
Silver electroplating :
White mate to very bright finish
Good corrosion resistance (depending on base metal)
Will tarnish easily
Hardness varies from 90 to 135 Brinnel
Excellent solderability (decreases with time)
Good lubricity and smear characteristics
Used as anti-galling on static seals, bushing, etc.
EXCELLENT electrical conductor
