Electropolishing of Nickel, Kovar or Stainless Steel Parts

We can perform electropolishing and cleaning of parts (or assemblies) composed of nickel, Kovar and/or stainless steel. We can provide this service economically whether it is for a single piece, just a few parts, or large amounts of parts. Please contact us for a free quote.

Electropolishing is an electrolytic method for reducing or eliminating surface irregularities without the introduction of any polishing compound particles into the surface. Our electropolishing process is preceded by a standard degreasing procedure. Pictured is a stainless steel piece, the left part of which has been electropolished.
