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)
