Electropolishing

We smooth, clean, and refine Nitinol and stainless components to meet demanding surface, purity, and performance standards.

Electropolishing for Nitinol, Stainless Steel, and High-Purity Applications

Electropolishing enhances surface finish by microscopically removing material, reducing roughness, and improving corrosion resistance. The process improves cleanliness, biocompatibility, and appearance—making it ideal for implantable and high-purity components.

Our electropolishing process enhances surface finish by selectively removing material at a microscopic level, reducing roughness and improving corrosion resistance. It is particularly effective for stainless steel and Nitinol components with fine features or tight tolerances. Electropolishing improves cleanliness, biocompatibility, and visual uniformity—critical for implantable and high-purity applications. The result is a smooth, consistent finish that meets stringent performance and aesthetic requirements.

Frequently Asked Questions

What is the primary benefit of electropolishing?

Electropolishing improves surface finish while removing micro-burrs, which can enhance fatigue life and corrosion
resistance.

Is electropolishing necessary for medical components?

Often, yes. Electropolishing can be necessary for medical components, especially where surface finish impacts performance, cleanliness, or biocompatibility.

How much material is removed during electropolishing?

Typically, the amount of material removed during electropolishing is minimal and controlled, and taken into consideration during tolerance stack-up.

Can electropolishing be combined with passivation?

Yes. Electropolishing and passivation processes are often used together for optimal corrosion resistance.

Does electropolishing improve consistency?

Yes. Electropolishing produces uniform surface finishes across complex geometries.
