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

Grade A
Mat – Electrodeposits without luster, obtained from electroplating solutions operated without the use of brighteners
Grade B
Bright – Electrodeposits obtained by the use of brighteners in the electroplating bath.
Grade C
Bright – Electrodeposits obtained by mechanical or chemical polishing of Grade A silver coatings
Grade D
Semi bright – Electrodeposit obtained by the use of addition agents in the electroplating bath.
Class N
A finish that has had no supplementary tarnish resistant (that is chromate) treatment
Class S
A – Finish that has had a supplementary tarnish resistant (that is, chromate) treatment.
