Electropolishing Services
Yonglihao Machinery offers electropolishing services to create cleaner, smoother metal surfaces with enhanced corrosion resistance. This process is ideal for parts requiring low surface roughness, easy cleaning, and a bright, uniform finish.
- Reduces micro-burrs and surface roughness
- Improves corrosion resistance for stainless and high-alloy metals
- Provides a cleaner, brighter appearance for visible or hygienic parts
What Is Electropolishing?
Electropolishing is an electrochemical finishing process that removes a controlled layer of metal from the surface using an electrolyte solution. It smooths microscopic peaks, reducing roughness and improving cleanliness.
This process is commonly applied to stainless steel and nickel-based alloys. It may also be used on other corrosion-resistant alloys upon review. The results depend on the alloy, initial surface condition, geometry, and target surface requirements.
One-Stop Manufacturing
We can perform electropolishing as a downstream step for parts made through:
Surface Preparation & Final Appearance
Electropolishing enhances smoothness but does not fix deep scratches, dents, pits, or major surface defects. The starting surface condition determines the final quality.
Edges and small features may be affected depending on the amount of material removed. For tight-tolerance fits, specify critical dimensions and acceptance criteria on the drawing.
| Surface Preparation | Applicable Materials | Visual Appearance | Typical Outcome | Notes |
|---|---|---|---|---|
| As-machined / cleaned | Stainless steel, nickel-based alloys | Brighter, smoother surface | Lower roughness, improved cleanability | Deep defects remain visible; geometry affects uniformity |
FAQ
What materials does electropolishing work on?
It is most commonly used on stainless steels and nickel-based alloys. Provide the grade for confirmation.
Does electropolishing improve corrosion resistance?
Yes, especially for stainless steel. A cleaner surface enhances corrosion resistance.
Will it remove scratches or dents?
It reduces micro-roughness but does not remove deep scratches, dents, or pits.
Can electropolishing change dimensions?
It removes a controlled amount of material. For tight fits, specify critical surfaces and acceptance criteria.
Is it suitable for medical or food-related parts?
Yes. Electropolishing is often used for parts requiring cleanability, smoothness, and corrosion resistance.
Can you electropolish welded parts?
Yes, but weld areas may show slight shade differences. Proper pre-cleaning is required.
What do you need for a fast quote?
We need the material grade, quantity, part size, surface target (Ra or cosmetic), critical fits, and lead time.
