FIELD: production of superhard materials and instruments on their base. SUBSTANCE: alloy of quasi-binary system TiNi-TiCo is proposed as binder for superhard material on the base of cubic boron nitride. Said alloy comprises, mas. %: Ti, 44.0-45,2; Co, 5-35; Ni, the balance. Superhard material having mentioned above binder may be used in blade cutting instruments which operate at cyclic impact stress. EFFECT: improved cutting ability of material at interrupted cutting. 1 tbl, 1 dwg
