Frequently Asked Questions

What is electropolishing and how does it work?

Electropolishing is an electrochemical metal finishing process that removes a thin layer of material from a metal surface to improve smoothness, corrosion resistance, and cleanliness. Parts are immersed in an electrolyte bath and exposed to direct current, which dissolves microscopic surface irregularities and creates a bright, uniform finish.

What are the benefits of electropolishing for stainless steel parts?

Electropolishing improves surface finish, enhances corrosion resistance, removes micro-burrs, and creates a clean, passive surface. It is especially beneficial for stainless steel components used in aerospace, medical devices, and other high-performance applications requiring strict cleanliness and durability.

What specifications does Rayco meet for electropolishing?

Rayco Metal Finishing performs electropolishing in accordance with ASTM B912 and supports a wide range of industry standards. Our processes are designed to meet strict compliance requirements for aerospace, medical, firearms, and OEM applications.

What types of parts are best suited for electropolishing?

Electropolishing is ideal for stainless steel and precision-machined components that require improved surface finish, corrosion resistance, and deburring. It is commonly used for medical devices, aerospace components, firearms parts, and complex geometries where uniform finishing is critical.

How do I know if electropolishing is the right process for my project?

If your application requires improved corrosion resistance, smoother surface finish, or enhanced cleanability, electropolishing may be the right solution. Rayco’s team works closely with customers to evaluate part requirements and recommend the best finishing process and specifications for your project.
