Brushing is a surface finishing process where abrasive brushes are used to produce uniform part surfaces of different roughness values. Brushing generates strokes in a unidirectional pattern and produces a satin finish. Abrasive brushes come in different grit numbers like sandpapers. Higher the grit number, the finer the surface produced by the abrasive brush.

Brushing of parts requires specific brushes depending upon the surface roughness and corrosion resistance requirements. If a part requires corrosion resistance, it has to be brushed with an abrasive brush of same material as itself. For example, a steel or aluminum part will require steel or aluminum abrasive brush to prevent corrosion. In general, when corrosion resistance is the primary requirement brushing is not suggested.
