FIELD: metallurgy.
SUBSTANCE: invention relates to powder metallurgy, particularly, to corrosion-resistant cemented carbides for production of components in contact with fluids, for example, sealing rings. Cemented carbide contains, wt. %; from about 7 to 11 % Ni; from about 0.5 to 2.5 % Cr3C2 and from about 0.5 to 1 % Mo; WC is the rest. Average WC grain size is not less than 4 mcm.
EFFECT: higher corrosion resistance and specific heat conductivity.
