Electropolishing is a reverse process to Electroplating - a cathode and anode system is used to remove material from the surface of the component being treated. Typically, between 20 and 40 Microns is removed, although as much as 75 Microns can be removed if necessary.

Stainless Steel can be very effectively Electropolished, so too can Nickel-Chromium alloys. It is also possible, with the correct choice of electrolyte, to Electropolish aluminium, brass and copper.

Electropolishing is a non-distortion process, so the parts do not undergo any thermal or mechanical stress during the process. The process does not distort the crystal structure of the material and leaves the surface completely featureless.
