Brushed Finish Supplier In China
A Brushed Finish is a premium surface treatment that creates a distinctive, unidirectional satin texture on metal parts. This is achieved by mechanically abrading the surface with a fine-grit abrasive, resulting in a pattern of very fine parallel lines that mimic the look of high-end stainless steel appliances and architectural hardware. As a quality-focused supplier in China, Celerity Precision offers expert brushing services to impart a sophisticated, decorative, and non-reflective look to your components, significantly enhancing their cosmetic appeal and perceived value.
For a distinctive, elegant, and perfectly uniform brushed finish, choose Celerity Precision as your dedicated manufacturing supplier.
Your Brushed Finish Manufacturer
At Celerity Precision, we are a manufacturer that treats a brushed finish not as a simple sanding job, but as a skilled, artistic process backed by industrial control. Our dedicated finishing department is equipped with specialized brushing and graining machines, as well as the expertise for manual application on complex surfaces. Our technicians meticulously control the grit of the abrasive, the pressure, and the speed of the stroke to create a perfectly consistent, linear pattern with the desired depth and luster. This craftsmanship ensures that the finish is uniform across the entire surface and consistent from part to part in a production run.
By managing both the CNC machining and the final aesthetic finishing, we take complete ownership of the final product’s quality. We understand that a perfect brushed finish starts with a perfectly machined surface, free of deep tool marks or defects. Our integrated workflow ensures that parts are prepared correctly before the brushing process begins. We can also combine brushing with other finishes, like anodizing or clear coating, to create a final product that is both beautiful and durable. Partner with Celerity Precision to manufacture components that make a powerful visual statement.

Brushed Finish: Technical Specifications
| Feature | Description |
| Surface Roughness (Ra) | The Ra value is moderate, typically ranging from 0.5 μm to 1.5 μm (20 μin to 60 μin). The goal is not smoothness in all directions, but a controlled, uniform roughness in a single direction. |
| Applicable Materials | Primarily used on metals where the grain can be showcased, including Aluminum, Stainless Steel, Brass, and Copper. |
| Cosmetic Availability | Superior. This is a purely decorative finish, chosen specifically for its high-end, sophisticated aesthetic. It is excellent at hiding fingerprints and small imperfections. |
| Visual Appearance | A satin, non-reflective finish characterized by very fine, parallel lines (the “grain”). The appearance changes subtly as the viewing angle and light source change, creating a dynamic and lustrous effect. The finish has a distinct directionality that follows the path of the abrasive. |
Advantages of a Brushed Finish
Elegant, High-End Aesthetic
Provides a sophisticated, decorative look that is associated with premium products, from luxury electronics to architectural fittings.
Hides Fingerprints and Minor Defects
The fine-lined texture is very effective at concealing smudges, fingerprints, and minor surface scratches, keeping the product looking clean.
Reduces Glare
The satin, non-reflective nature of the finish minimizes glare and distracting reflections, which can be beneficial for user interfaces and instrument panels.
Creates a Tactile Experience
The subtle texture provides a pleasing tactile feel that can enhance the user's perception of quality.
Durable and Easy to Maintain
The finish is inherently durable, and small scratches that occur during use tend to blend in with the existing grain, making it easy to maintain.
Consistent and Repeatable
When performed with industrial equipment, the finish is highly consistent and can be reliably reproduced across large production volumes.
Brushed Finish Design Considerations
Direction of the Grain
The direction of the brushed lines is a key aesthetic choice and must be specified on the drawing (e.g., "Brush parallel to the longest edge").
Line of Sight Process
Brushing is a direct contact, line-of-sight process. It is best suited for flat or gently curved external surfaces. It cannot be applied to internal cavities or complex, recessed areas.
Edge Softening
The abrasive process will naturally soften or "break" sharp edges, creating a small radius. This should be considered in the design.
Pre-Finish Surface Quality
A high-quality brushed finish requires a good underlying surface. Deep tool marks or scratches from the machining phase must be removed before brushing can begin.
FAQ
Is a brushed finish the same as a satin finish?
They are related but not identical. A satin finish is a general term for a non-glossy surface. A brushed finish is a specific type of satin finish, characterized by its visible, unidirectional lines.
How do you create a brushed finish?
It is created by moving a fine-grit abrasive (like a Scotch-Brite™ belt or wheel) across the metal surface in a controlled, linear motion.
Will the brushed finish rust?
The finish itself does not provide corrosion protection. On a material like aluminum, it will be naturally corrosion-resistant. On stainless steel, it is fine. On regular steel, it would need a protective clear coat to prevent rust.
Can you brush plastic parts?
No, brushing is a process for metals. Attempting to brush plastic would typically melt or gouge the surface rather than creating a clean grain.
How do I specify the direction of the brushing?
Use arrows or notes on your technical drawing. For example, for a rectangular plate, you can specify “Brushed finish parallel to the 400mm dimension.”
Can you brush curved or round parts?
Yes. Round parts can be brushed circumferentially on a lathe (“spun finish”), and gently curved surfaces can often be brushed by skilled technicians or with specialized equipment.
Does brushing remove a lot of material?
No, it is a very light abrasive process that removes a negligible amount of material. It does not significantly alter part dimensions.
How do I clean a product with a brushed finish?
It’s best to clean in the direction of the grain using a soft cloth and a mild cleaner. This prevents dirt from getting trapped in the fine lines and avoids creating cross-grain scratches.
Can a brushed finish be anodized?
Yes, absolutely. Brushing aluminum and then anodizing it (often with a clear or light-colored dye) is a very popular combination that creates a beautiful, durable, and premium finish.
How do I specify a brushed finish on my drawing?
A clear note is best: “Brushed Finish, 180 grit, parallel to longest edge.” This tells us the texture, the direction, and ensures a consistent result.
