- The brush is usually made from a large number of steel wire bristles.
- The steel used is generally a high carbon variety and very hard.
- Other wire brushes feature bristles made from brass or stainless steel or nylon, depending on application.
- Wires in a wire brush can be held together by epoxy, staples, or in some cases one continuous wire.
