ABSTRACT:
The present invention relates to a cemented carbide body, preferably for rock drilling, mineral cutting and wear parts, in which the content of binder phase in the surface is lower and in the center higher than the nominal content. In the center there is a zone having a uniform content of binder phase. The WC grain size is uniform throughout the body.
