FIELD: metallurgy.
SUBSTANCE: invention relates to powder metallurgy, and namely to hard alloys on the basis of tungsten carbide. It can be used at cutting of materials. Hard alloy contains the following, wt %: tungsten 78.0-80.2, carbon 5.6-5.8, molybdenum 5.7-7.0, cobalt 8.0-8.4 or tungsten 77.0-78.5, carbon 7.0-7.2, molybdenum 2.9-3.2, cobalt 8.1-8.4, and titanium 3.5-3.8.
EFFECT: providing improvement of coefficient of stability and preservation of mechanical properties of an alloy at its cheapening.
