Beschreibung
Zusammenfassung:	A superhard composite material comprises cubic boron nitride and a binder consisting of carbide and diboride of a metal selected from the group IV-V of the periodic system, taken in eutectic ratio, the components being contained therein in the following amounts, in percent by weight: cubic boron nitride: 28 to 80 carbide and diboride of a metal selected from the group IV-V of the periodic system, taken in eutectic ratio: 72 to 20 The proposed material has high heat, and electrical conductivity, as well as high wear resistance and low brittleness.
