Brushed + Electropolishing

What is Brushed Electropolishing?

Brushed Electropolishing is a hybrid surface finishing process that combines mechanical brushing with advanced electrochemical leveling to produce a clean, smooth, and corrosion-resistant surface. It improves both appearance and performance, making it suitable for high-precision components in medical, aerospace, food processing, and semiconductor applications.

This is initiated by a brushed surface finish and then electropolishing, which refines the surface on a microscopic scale. The result? Better cleanliness, luster, and service.

Why Choose Brushed Electropolishing for Your Parts?

• Electrostatically removes micro-burrs and Contaminants
• Resistance to corrosion
• Leaves a non-directional finishing Baker
• Applicable to intricate shapes

If you’re wondering: Can Brushed‑EP achieve mirror finish?,  the reply is yes! When precision brushing is used before electropolishing, especially, the final result can approach or even surpass the reflectivity of a mirror, depending upon material and Ra requirements.

Brushed Electropolishing vs Brushed Finish Alone

Many industries still rely on standard brushed finishes, but brushed+EP vs brushed shows a dramatic improvement in surface integrity, longevity, and cleanliness.

This makes Brushed Electropolishing the go-to for critical applications where hygiene and durability are paramount.

What Ra After Brushing Before EP?

A common question among engineers is: “What Ra after brushing before EP?” The brushing procedure normally leaves the surface roughness (Ra) between 0.3 and 0.6 µm. This is an optimum range because it provides the electropolishing process with sufficient texture to level properly without compromising the surface integrity. Surfaces after EP may have an Ra of 0.13 or less.

Industry Application  of Brushed Electropolishing  

Brushed Electropolishing is widely used in:

• Medical equipment (implants, surgical equipment)
• Food & beverage processing equipment
• Pharmaceutical equipment
• Semiconductor manufacturing
• Aerospace components

This process provides each of these industries with the ultra-smooth finish, lowered bacterial retention, and increased life of parts.

Electrochemical Leveling: The Science Behind the Shine

The electropolishing step uses electrochemical leveling to remove a thin layer of metal, targeting surface peaks more aggressively than valleys. This smoothens the surface on a microscopic scale, decreasing Ra and increasing reflectivity. This works particularly well when applied after brushing, when a uniform texture is produced, which EP can smooth out to perfection.
