According to the invention there now exists a sintered titanium based carbonitride alloy containing hard constituents with core-rim structure based on, besides Ti and W and/or Mo, one or more of the metals Zr, Hf, V, Nb, Ta or Cr in 5-30 weight% binder phase based on Co and/or Ni with simultaneously increased wear resistance and toughness. The alloy is characterized in that at least 70 %, preferably at least 80 %, of said hard constituents has four different types of cores with the following contents of Ti and W in weight% of the total metal content: 1-5 W and 90-95 Ti(1A), 15-25 W and 65-85 Ti(1B), 50-75 W and 20-40 Ti(1C) as well as 20-30 W and 30-60 Ti(2A), whereby the share of each type amounts to at least 5 %. <IMAGE> |
