Electropolishing is an electrochemical finishing process that removes a thin layer of material from a metal part, typically stainless steel or similar alloys. The process leaves a shiny, smooth, ultra-clean surface finish.
Electropolishing can be thought of as reverse electroplating. Instead of adding a thin coating of positively-charged metal ions, electropolishing uses electric current to dissolve a thin layer of metal ions into an electrolyte solution.
Electropolished Stainless Steel Tubing is used for biotechnology, semiconductor and in pharmaceutical applications.
