FIELD: powder metallurgy, production of electrode-tools for electroerosion treatment. SUBSTANCE: method to produce composition material, based on tungsten-copper pseudoalloy, provides for charge pressing and its thermal treatment. In the case, charge has, in mass tungsten concentrate reduction powder 20-27; baddeleyite concentrate powder 3-10; copper powder the rest. Product of tungsten considerate reduction has, in mass tungsten - 74-75; iron 6.-6.5; calcium oxide 16-17; silicon oxide 2.0-2.5; baddeleyite concentrate with 98 mass of zirconium; the rest - components, taken from group oft hafnium, silicon, manganese, titanium and iron. Produced electrode-tool, based on pseudoalloy of tungsten-copper with zirconium oxide, showed increased operational features during hard alloy processing and has lower production cost. EFFECT: method provides better operational features and lower production costs. 2 cl, 1 tbl
