Carbon Brush with Metallic Layers

Carbon brushes made of multi-layer materials are pressed together directly and then thermally treated. The process for creating multi-layer materials simplifies the joining of materials with different properties into a carbon brush. Functional layers which include some copper have a similar effect to metalized surfaces (galvanically or chemically copper-plated or coated with conductive silver paint) to increase efficiency or reduce the temperature.

You benefit from these advantages:

• Perfectly matched material with pressed-in metallic layers
• Multiple material properties combined in a single carbon brush
• Functional layers for reducing radio frequency interference (RFI) emissions (power-transfer layer and commutation layer)
