KN20
- Special Grade
- Nonmagnetic cemented carbide
Nonmagnetic and corrosion resistance.
This material has specific improved performance compared to ordinary materials, and it has the ability to solve many problems today.
With its long lifespan, you can lower your material costs.
| Application | Magnetic field mold, tools for magnetic tape, electronic equipment, parts for chemical instruments, mechanical tools, decorative parts, etc. |
|---|---|
| Characteristic | Nonmagnetic with superior corrosion and heat resistance due to Ni replacing the bonded phase. |
