El metal duro compuesto ROCTEC® es un material que se basa en el metal duro al tungsteno, fabricado con el proceso de compactación direccional Rapid Omni (ROC); solo Kennametal dispone de la licencia para usar estos productos.

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.
