What is Electropolishing?

Electropolishing, also known as electrochemical polishing, is an electrochemical process that removes surface imperfections and impurities such as burrs, microcracks, stains, heat tint, and oxide scaling from components, parts, and equipment made of a wide variety of metals. Electropolishing leaves vital parts and critical components ultra-clean, super-smooth, and highly resistant to corrosion.

How does Electropolishing Work?

Here’s how electropolishing works: Metal parts are placed and secured in a special rack, then submerged into a specially blended chemical bath. An electrical current is applied to the part. The charge causes a chemical reaction that smooths the part’s surface by removing an extremely thin layer of metal at a controlled, uniform rate. The electropolishing process can be monitored and completed to meet exacting specifications for cleanliness, smoothness, and corrosion protection. Your stainless steel — such as 300 series and 400 series stainless steel — and other metal parts, components, and equipment need to be as perfect as possible.

Microscopic cracks, bumps, and burrs on life-saving surgical instruments, intricate avionics, and sensitive nuclear reactor piping can cause major problems. For more than two decades, Electro-Max, Inc. (EMI) has delivered high-quality electropolishing, or electrochemical polishing, services that expertly, efficiently, and effectively eliminate surface imperfections and impurities that can compromise the fit, finish, function, and durability of parts made of stainless steel, titanium, nickel, aluminum, and other metals.
