Electrolytic polishing, also known as electropolishing, is a process used to smooth, polish, and deburr metal surfaces by removing a thin layer of material through an electrochemical reaction. While stainless steel is the most commonly electropolished material, the process is compatible with a wide range of metals, including aluminum, brass, carbon steels, cobalt chrome, copper alloys, nickel alloys, titanium, and Nitinol. Each of these materials benefits from electropolishing in unique ways, such as improved corrosion resistance, enhanced surface finish, and reduced friction. The process is particularly useful for applications requiring high precision and cleanliness, such as in medical, aerospace, and food processing industries.
