Abstract

PURPOSE:To obtain a dental Ni alloy for casting having a relatively low m.p. and capable of using a gypsum filler by alloying Ni with a specified amount of Cr, Cu, Mn, Al and Si or further adding one or more among Ca, Ge, Nb and Zr. CONSTITUTION:This Ni alloy for casting as starting material for dental filling such as a crown or a bridge contains 7-30% Cr, 3-25% Cu, 5-30% Mn, 0.1-4% Al and 0.1-4% Si or further contains one or more among 0.5-10% Ca, 0.5-10% Ge, 0.5-5% Nb and 0.5-5% Zr. This alloy has <=1,200 deg.C m.p. and can be melted with a mixed flame of town gas and oxygen. A gypsum filler can be used in the alloy, and the alloy is easily polished and does not discolor in the mouth.
