Abstract
Nozzles for plasma torches are essentially formed from a metal or a metal alloy. To increase the life of such nozzles wear-resistant microparticles of a hard material, preferably a hard ceramic material, are embedded in the metal or the metal alloy, at least in certain regions. The nozzles can be advantageously manufactured by extrusion.
