Abstract:
A cemented carbide material comprising tungsten carbide grains, the content of tungsten carbide in the cemented carbide material being at least 75 weight percent and at most 95 weight percent. The cemented carbide material comprises a binder phase comprising any of cobalt, iron, or nickel, and nanoparticles. Te nanoparticles include material according to the formula Co x W y C z , where x is a value in the range from 1 to 7, y is a value in the range from 1 to 10 and z is a value in the range from 0 to 4. The nanoparticles have a mean grain size of no more than 10 nm and at least 10 percent of the nanoparticles have a size of at most 5 nm. The volume percent of the tungsten carbide grains having a grain size of no more than 1 μm is less than 4 percent. A method for producing the cemented carbide material is also disclosed.

Claim (Index 7):
The cemented carbide material as claimed in  claim 1 , in which the tungsten carbide particles have a mean size D of at least 4 microns and the cemented carbide material has a magnetic coercive force Hc (in kA/m) of at least 1.1\u00d7(100\u00d7[Co])\u22121.2/D+3.3), where D is in microns, and [Co] is the weight percent of cobalt in the cemented carbide material.
