A Ni-Cr based alloy not containing precious metals has been developed for prosthetic dentistry uses. The alloy is characterized by high hardness, good workability, high corrosion resistance and optimal adherence to ceramic materials. The alloy consists essentially of: Cr 22.0 -25.0 % weight Mo 5.5 - 7.5 % weight Si 2.0 - 4.5 % weight B 0.25 - 0.50 % weight Al /= 0.2 % weight Fe /= 0.5 % weight C /= 0.05 % weight Cu /= 0.5 % weight Mn /= 0.5 % weight S /= 0.01 % weight Rare earths 0.005 - 0.2 % weight Remainder Ni and impurities.
