Power Brushes Fill Material

The filament is the working action of the brush and deserves plenty of attention in designing your power brush. Each filament material offers specific benefits and selection is determined by the purpose the brush serves. We have standard power brushes available in carbon steel, stainless steel, brass wire, encapsulated carbon steel, urethane encapsulated carbon, urethane encapsulated stainless steel, bristle, black nylon type 6-12, Tampico, abrasive nylon and natural filaments like horse hair.

Wire filaments are often used in power brushes due to the sharpness and aggressiveness of their cutting surfaces. The harder wires like carbon steel and stainless steel are used on scratch-resistant surfaces, while softer wires like brass are used on more vulnerable surfaces and in non-sparking environments.

When extremely durable and aggressive filament is required one of our two abrasive nylon filament types is used:

• Silicon Carbide is harder, sharper and more aggressive than aluminum oxide and is preferred for finishing ferrous metals. Silicon carbide is generally available in 500 to 46 grit and diameter ranges from .018” to .060”.
• Aluminum Oxide is more impact resistant compared to silicon carbide and is less likely to fracture and is preferred for finishing soft metals or other materials where a smooth finish is required. Aluminum oxide is generally available from 600 to 80 grit and diameter ranges from .012” to .040”.

When polishing softer and more scratch-susceptible surfaces, nylon filament is typically recommended. Also, tampico is the ideal filament if the environment requires a filament that is resistant to moisture. Our technical sales team and engineers are always available to assist you in selecting the right filament for your application.
