## Specifications

| Spec | Value |
|---|---|
| Coating thickness | No coating — removes <10 µm and leaves a directional #4-equivalent satin grain at Ra 0.4–0.8 µm on the brushed faces. |
| Tolerance impact | Negligible on rigid parts — removal stays under 10 µm. Thin panels (<2 mm) can pick up slight bow from one-sided brushing stress; toleranced faces tighter than ±0.02 mm should be masked or verified after brushing. |
| Corrosion rating | Unchanged — corrosion behavior stays that of the base metal. On aluminum, pair with clear anodizing; on stainless, brushed #4 is a finished standalone surface. |
| Appearance | Linear satin grain that catches light along one axis — the classic look of premium appliances, audio gear and architectural stainless. Grain direction is a design decision: specify it relative to the part’s long axis or visible edge. |
| Applicable substrates | aluminum, stainless-steel |

## Not suitable for

Three-dimensional curved surfaces — the grain can only run in one direction on flat or gently curved faces; pocket and recess interiors keep the machined finish (the brush cannot enter them); parts where every face must look identical (combine with bead blasting for a deliberate two-texture design instead).

## Typical applications

- Front panels and bezels
- Audio equipment faceplates
- Architectural and signage hardware
- Appliance trim and handles
