This stainless instrument bezel had a light burr on the inside and outside edge. Electropolishing greatly reduced the burr and cleaned the part in one operation. This was done without distortion or warping that would occur with vibra finishing or hand polishing.

This very heavy gauge stainless part needed to be clean and smooth. Normal mass finishing would have impinged or scratched the surfaces. Electropolishing uniformly treated surfaces inside and out, including the tough inside bend near the top.

These return springs are made of stainless steel. Electropolishing removed surface scale and discoloration, exposing the true base metal. Metal was removed uniformly on all the complex surfaces.

Made from brass, this small part shows how electropolishing can smooth and clean this difficult alloy. Ra values are normally improved by 50%. While the native brass surface resists tarnish, we recommend a protective coating in applications requiring a tarnish free appearance.

This aluminum part has been partially electropolished to show surface improvement. Formed from 1100 aluminum, surface oxides were removed and the part was left totally clean. Unlike most mechanical finishing methods, electropolishing does not bend or distort the soft aluminum component.

This copper ring offers an excellent example of the cleaning properties of electropolishing. By removing surface metal from the entire surface simultaneously, oxidation, absorbed chemical and imbedded contamination were removed with minimal dimension change. We electropolish a wide range of copper components for sensitive electronics semiconductor and aerospace/defense assemblies.
