Graphite powder used in carbon brushes has specific advantages:

1. Good Conductivity: Provides excellent electrical conductivity for efficient performance.

2. Smooth Operation: Reduces friction and wear, leading to longer-lasting brushes.

3. High Temperature Resistance: Withstands high temperatures without degrading.

4. Lubrication: Acts as a natural lubricant, reducing friction between the brush and the commutator or slip ring.

5. Consistent Quality: Ensures reliable and uniform performance in various electrical applications.
