Abstract

PURPOSE:To obtain a dental magnetic alloy with a low m.p. and superior castability by adding Pd, Au and Si to Co or Ni in a specified ratio. CONSTITUTION:This dental magnetic alloy consists of, by wt., 30-73% Pd, 5- 10% Au, <=5% Si and 20-60% Co or Ni. The restricted Co or Ni content adjusts the melting temp. of the alloy to <=1,350 deg.C, and Co or Ni alloyed with Pd provides high corrosion resistance. The addition of Au lowers the m.p., improves the casting surface, and raises the casting accuracy. Si has the effect of improving the castability and reducing blow holes. By this composition the casting timing is easily judged.
