Cemented carbide

The present invention relates to a cemented carbide body containing from about 3 to less than about 15 wt-% binder phase and essentially WC as the remainder. By alloying the binder phase with from about 0.5 to about 15 wt-% Mn an increase in the strength of the WC/WC grain boundaries is obtained.
