NICKEL-BASE ALLOY FOR CERAMIC-MIMIC STOMATOLOGICAL ARTICLES Russian patent published in 2006 - IPC C22C19/05 A61K6/04 

FIELD: metallurgy, medicine, stomatology.

SUBSTANCE: invention relates to alloys used in stomatology for making dental crowns, prosthesis, clasps and others articles by casting technology. Invention proposes nickel-base alloy for ceramic-mimic stomatological article that comprises the following components, wt.-%: chrome (Cr), 13.6-14.8; molybdenum (Mo), 7.4-8.6; niobium (Nb), 0.5-0.9; aluminum (Al), 1.3-1.6; carbon (C), 0.1-0.2, and nickel (Ni), the balance. Invention provides the optimal combination of properties required in orthopedic stomatology for casting allays, namely, high level of hardness, strength and fluidity limit, and improved adhesion with ceramic layers, and the minimal toxicity.

EFFECT: improved and valuable properties of alloy.
