For your Silver Plating requirements, ProPlate® has facilities for silver electroplating both small and large parts in various sized barrels and racks, along with custom and prototype metal finishing.
Silver plating offers the highest electrical conductivity of all metals. It is not a precious metal and will oxidize rapidly. Silver plating is best suited for engineering purposes for solderable surfaces, electrical contact characteristics, high electrical and thermal conductivity, thermocompression bonding, wear resistance of load-bearing surfaces, and spectral reflectivity electrical applications, good corrosion resistance, good solderability, and other applications.

Specification: Mil-QQ-S-365 Silver Plating, Electrodeposited
Several options are available as supplementary coating for increasing tarnish resistance. Depending on solder-ability, or subsequent finishing steps such as painting or powder coating, we will recommend specific coatings.
For applications where corrosion protection is important, the use of silver plating with an electrodeposited nickel undercoat is advantageous.
Silver plating on steel, zinc and zinc-based alloys should have an undercoat of nickel over copper.
Silver plating on copper and copper alloys should have a nickel undercoat. Copper and copper alloy material on which a nickel undercoat is not used, and other base metals where a copper undercoat is employed, should not be used for continuous service at a temperature in excess of 300 degrees F (149 degrees C). Adhesion of the silver plating is adversely affected because of the formation of a weak silver and copper inter-metallic layer.
