FIELD: metallurgy, medicine, stomatology.
SUBSTANCE: invention relates to nickel-base alloys used in making tooth crowns, prosthesis and clasps. Invention proposes alloy for stomatology comprising chrome, molybdenum, carbon and nickel and comprising additionally niobium and cobalt in the following ratio of components, wt.-%: chrome (Cr), 22.1-23.4; molybdenum (Mo), 8.8-9.6; niobium (Nb), 3.3-3.7; cobalt (Co), 3.0-4.0; carbon (C), 0.1-0.2, and nickel (Ni), the balance. Invention provides the optimal combination of alloy property for stomatological articles, in particular, its strength indices and anti-corrosion resistance.
EFFECT: improved and valuable properties of alloy.
