E.D.M. Graphite
Electrical Discharge Machining (EDM), the dominant electrode material displacing copper and copper alloy materials
Advantages of Graphite EDM Electrode
- Good machinability
- High resistant to thermal shock
- Low coefficient of thermal expansion (3X lower than copper)
- Density 5X lower than copper
- Provides higher metal removal rate than copper
- Unique characteristic that the wear ratio tends to decrease as the peak current increases
