Across aerospace, medical, automotive and many other industries, electropolishing is the preferred finishing method for fasteners and other critical metal parts. When there’s no room for error, electropolishing smooths the surface of fasteners to improve the corrosion resistance, durability and finish of these key components.

Through a process sometimes referred to as "reverse plating," electropolishing combines a chemical bath with an electrical current to strip away a precise layer of material from the surface of metal parts. The process works with a variety of alloys, including stainless steel, aluminum, titanium and more.

Electropolishing eliminates surface imperfections caused by the machining processes, including microcracks, microburrs, scale and other contaminants. Electropolishing’s precision leaves parts with significantly enhanced corrosion and pathogen resistance and a microscopically smooth surface, with 30–50% improvement in the part’s Ra (roughness average), depending on material type.

In our latest white paper, we cover the key benefits of electropolishing for fasteners, including:

  • Corrosion resistance
  • Elimination of galling
  • Microscopic precision
  • High shine

As a more precise alternative to passivation, electropolishing eliminates microscopic defects to create an ultra-smooth, hygienic surface. To learn more, read our white paper: Electropolishing for Improved Fit, Function and Appearance of Metal Fasteners

Our video, the Electropolishing Advantage, will take you through the many benefits of this microscopically precise and highly customized finishing method including:

  • Enhanced corrosion resistance
  • Improved cycle life
  • Ultrasmooth and shiny surface finish
  • Enhanced pathogen resistance

We’ll walk you through our "Finish First" methodology, which provides consultation in the prototyping stage to eliminate design flaws that could impact finishing results. Our team works closely with clients to optimize the finish of your part for longevity and functionality. The result is an ultrasmooth, ultraclean and more durable metal part.
