PRODUCT INTRODUCTION
Low Friction Cemented Carbide for Motor Core Molds
PRD12N
- Corrosion
Resistance - Wear
Resistance - Seizure
Resistance
“PRD12N is a new grade for motor core molds, which is fuctionally desinged from P Series, our original low friction grade.
And, it is suitable for punching electromagnetic steel sheets.
