Abstract
A multi-metal powder, in particular for producing diamond tools comprises iron copper, cobalt and molybdenum whose contents are expressed in the following mass percentages: Fe+Cu+Co+Mo=98 mass %, the rest being oxygen and production impurities, wherein 15%=Cu=35%, 0.03=Mo/(Co+Fe+Mo)=0.10, —Fe/Co=2. A sintered compact is obtained by hot compaction of said multi-metal powder, for example, in the form of a diamond cutting tool.
