Abstract

PURPOSE:To obtain a dental magnetic alloy with a low m.p. and superior castability by adding Pd and Si to Co and Ni in a specified ratio. CONSTITUTION:This dental magnetic alloy consists of, by wt., 20-35% Co, 20- 40% Ni, 25-60% Pd and <=0.5% Si or further contains 5-20% Au as required. Co alloyed with Pd provides high corrosion resistance and adjusts the solidus point to <=1,350 deg.C. Ni has the effect of enhancing the corrosion resistance and hardness and improving the suitability to porcelain baking. Si has the effect of improving the castability and reducing blow holes. The addition of Au lowers the solidus point, improves the casting surface, and raises the casting accuracy. By this composition the casting timing is easily judged.
