PRODUCT INTRODUCTION
Low Friction Cemented Carbides with Excellent Balance of Characteristics
PRD Series
- Corrosion
Resistance - Wear
Resistance - Seizure
Resistance
PRD Series exhibits excellent balance of strength, wear resistance and toughness by adopting medium grained WC. Furthermore, it also excels in seizure resistance by adding low-friction to RD Series while retaining the original characteristics. It is used in a wide range of applications, from various wear-resistant tools to blades and machine parts.
