EF grade
- Micro-grain Cemented Carbide
- For cutting tools
Superior high chipping resistance.
| Application | For lead frames, connectors, and other metal mold electronic components. |
|---|---|
| Characteristic |
Micro-grain Cemented Carbide with WC particle diameter smaller than 1 μm. Perfect for use where a sharp edge is required, as it is extremely hard and has a high transverse rupture strength. Newly-developed EF01 has a hardness (HV) of 2000, realizing an extremely hard material with superior wear resistance. |
