Carbon Brush Material Comparison
- Graphite Carbon Brush
• Advantages: Stable conductivity, low friction, economical, suitable for long-term operation.
• Disadvantages: Lower current capacity, not ideal for heavy-duty equipment.
• Applications: Printers, light-duty generators, precision instruments.
- Semi-Copper Carbon Brush
• Advantages: Balanced conductivity and wear resistance, reliable performance, longer service life.
• Disadvantages: Higher friction than graphite, not suitable for very high-speed motors.
• Applications: Standard diesel generators, industrial machinery, general motors.
- High-Copper Carbon Brush
• Advantages: Excellent conductivity, strong current capacity, high durability under heavy loads.
• Disadvantages: Faster wear, may cause more wear on the commutator.
• Applications: Large diesel generators, heavy-duty motors, metallurgy and mining equipment.
🌟 Summary
• Graphite → Stable & light load
• Semi-Copper → Balanced & general use
• High-Copper → Strong current & heavy-duty
