Zusammenfassung:	In order to provide a nonmagnetic material for producing parts or coatings adapted for highly wear and corrosion intensive applications, said material comprising pre-formed particles made of tungsten carbide which are embedded in a metal phase made of a Ni-based alloy. It is suggested that the weight portion of said tungsten carbide particles is in the range between 30 wt.% and 65 wt.% and wherein the Ni-based alloy is a Nickel - Chromium - Molybdenum alloy comprising: (in wt.%): Cr 11,0, - 30,0, Mo 5,0 - 25,0, Fe 0 - 10,0, B 0 - 5,0, Co 0 - 2,5. L'invention concerne un matériau non magnétique permettant de fabriquer des pièces ou des revêtements adaptés à des applications entraînant une usure élevée ou une corrosion intensive, ledit matériau comprenant des particules préformées faites de carbure de tungstène incorporées dans une phase métallique faite d'un alliage à base de Ni. La proportion pondérales desdites particules de carbure de tungstène se situe entre 30 % et 65 % ; l'alliage à base de Ni est un alliage Nickel-Chrome-Molybdène comprenant (% en poids) : Cr 11,0, - 30,0, Mo 5,0 - 25,0, Fe 0 - 10,0, B 0 - 5,0,0 Co 0 - 2,5.
