High Precision EDM Graphite Electrode with High Purity (99.9-99.99% Carbon) and Smooth Surface Finish for Mold Making
| Comparison Parameters | Advantages |
|---|---|
| Production costs | Graphite of the same volume costs only about 25% that of copper electrodes. |
| Machining Speed | The machining speed is 3–5 times faster than copper electrode, the machined surface is smooth. The electric discharge machining speed is 1/3 to 2 times faster than that of traditional copper electrodes, making it more suitable for rough machining. |
| Machining accuracy | Good machining precision, C.T.E is 1/4 of copper, easy polishing. |
| Weight | The density of graphite is only 1/5 of copper, it's more suitable in the production for larger electrode. |
| Loss | Used as EDM electrode, which consumption is only 1/3–1/5 of copper electrode, the coating of spark decomposition of carbide compensates electrode loss. |
| High temperature resistance | The melting point of graphite is up to 3650℃, with no deformation under high-temperature working conditions, and more suitable for machining bone electrode. |
| Electrode Cohesiveness | Damaged graphite parts can be bonded with conductive adhesive, effectively saving production time and reducing material costs. |
