ROCTEC® Composite Carbide for Abrasive Waterjet (AWJ) Applications

ROCTEC® abrasive waterjet (AWJ) nozzles are made from our proprietary process combining advanced materials without the need for a soft metal binder, as with traditional sintering technology using tungsten carbide/cobalt.

Together, our unique material and process technologies minimize nozzle wear, which allows longer cutting periods while maintaining precision performance. This same advantage in technologies ensures consistency in each nozzle, eliminating the need to reprogram a job when replacing a nozzle. 

The ROC Process

ROCTEC® composite carbide is a tungsten carbide-based material made by the patented Rapid Omnidirectional Compaction (ROC) process exclusive to Kennametal.

This process enables these advanced ceramic materials to be combined without using a soft metal binder and with very short consolidation cycles - minimizing the natural tendency of ceramic particles to enlarge when exposed to high heat for long periods.

Maintaining extra-fine grain size means better nozzle performance resulting in an extremely durable material that fiercely resists abrasive and erosive wear.

Superior Wear Resistance & Greater Accuracy

Superior wear resistance means a reduction in the number of AWJ nozzles purchased over time. Longer AWJ nozzle life also results in a better jet pattern and increased velocity. This means faster average cutting speeds and significantly less downtime for nozzle replacement and system calibration.

This also translates to greater dimensional accuracy and the ability to perform longer, uninterrupted cuts. These enhancements ensure a more cost effective cutting process.
