PCD Grades for Turning Non-Ferrous Materials • Two PCD grades — WDN25U and WDN00U — cover a wide range of applications. • Grades provide outstanding performance to increase productivity and cut manufacturing costs. • High abrasion and chipping resistance. • Used in machining aluminium alloys with low- and high-silicon content, copper alloys, ceramics, and plastics. • Suitable for machining highly abrasive materials such as titanium and Metal Matrix Composites (MMC). WDN25U™ • Multi-modal grade. • Versatile grade for general machining applications. • Withstands moderate interruptions. WDN00U™ • Ultra-fine grain grade. • Ideal for high-speed finishing operations. • F ine grain structure provides a finer edge prep and better surface finish.
