Best materials for Electric-Charge and Non-Electric Charge Brushes

Because some brushes are best suited for specific applications, custom industrial brushes should be chosen with care. Every time a brush moves across a dry surface, it creates an electrical charge. In some industrial environments, this charge can be extremely dangerous. In manufacturing facilities where military grade weapons are made, for example, an electrically charged brush could become lethal. A single spark could set off a chain reaction of events that have the potential to end lives.

The best preventive measure is to use anti-static brushes. Those with natural fibers may be made of tampico, hog bristle, horse hair or goat hair. These tend to be high-end in terms of cost, so companies tend to choose those that are less expensive to replace after they undergo some wear. Nylon is a popular material for synthetic brush fibers. They are commonly used in cleanrooms since they are less vulnerable to contamination. If a task calls for conducing electric charges through a metal brush, the typical types are aluminum, brass, stainless steel or phosphor bronze. The same metals are used in the handles of these conductive brush types. Other non-electric charge brushes are made of wood or plastic, which can be altered to conduct a charge if necessary.

One other tip to remember about conductive brushes is that they should have small diameter fibers to slow down abrasion. Brushes used for non-electronic tasks should have large diameter fibers in order to make the brush stiff. Adhering to suggested diameters for fibers will lessen the wear on the brush.
