Scratch brush is a type of brush that has a stiff and coarse wire fiber that is used to produce fine scratches or scratches on the surface of the workpiece. These brushes are generally used in the process of sanding, cleaning or surface preparation prior to plating or welding.
Scratch brushes have a sturdy handle and wire fibers extending from one or both ends of the brush. The wire fibers can be made of steel, stainless steel, or even copper depending on the application requirements.
When in use, the scratch brush is moved by a frictional motion or brush on the surface of the workpiece. Stiff, coarse wire fibers can remove rust, dirt, or other layers of material and impart texture or scratches to the surface.
Scratch brushes are generally used on metals, such as steel or aluminum, to clean surfaces before welding or plating. They are also used to clean and remove old paint, oxides, or other contaminants on metal surfaces.
