ROCTEC Composite Carbide:
The Ultimate Wear Material
ROCTEC™ abrasive water jet (AWJ) nozzles are
made from unique materials that have literally
changed the definition of wear resistance.
ROCTEC™ composite carbide is a tungsten carbide
based material made using the proprietary Rapid
Omnidirectional Compaction (ROC) process.

ROCTEC Waterjet Nozzles™

The ROCTEC process enables the combinationof these advanced ceramic materials without theneed for a soft metal binder, as is the case withtungsten carbide/cobalt using traditional sintering
technology. The ROC process enables nozzles tobe formed using very short consolidation cycles tominimize the natural tendency of ceramic particles
to grow in size when exposed to high heat forlong periods. Eliminating a metallic binder andmaintaining extra-fine grain size both contributeto optimum nozzle performance. The result is anextremely durable material that fiercely resists
abrasive and erosive wear.

Inspect orifice for chipping, wear and/or buildup of dirt or abrasive•

Use mixing chamber components made from carbide or ROCTEC•

Verify water - orifice alignment prior to abrasive selection•

Precise alignment of the orifice and focusing tube ensures the jet is focused directly down the center of tube•

ROCTEC focusing tubes with precise alignment will allow the longest life and highest level of cutting quality
