Brushed Finish
The appliance-grade look: directional satin grain on panels, bezels and show faces.
Process specifications
| Parameter | Value |
|---|---|
| Process group | Mechanical Finishes |
| 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. |
⚠ 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).
