Silver Plating

Silver has long been valued as a precious metal. Silver is used industrially in electrical contacts and conductors

The electrical conductivity of Silver is the highest of all metals, even higher than copper, but it is not widely used for electrical purposes due to cost and issues with oxidation which now can be minimized with a anti-tarnish coating. 

An exception to this is in radio-frequency engineering, particularly at VHF and higher frequencies, where Silver plating is employed to improve electrical conductivity of parts and wires (at high frequencies current tends to flow on the surface of conductors, not their interior, hence Silver-plating greatly improves overall conductivity). Silver also has the lowest contact resistance of any metal.

At Foresight we can plate extremely small parts with tolerances as tight as +/- .0002.
