ABSTRACT:
Non-precious dental casting alloys containing about 67-73% nickel, about 18-24% chromium, about 1.85-2.5% silicon, about 2.5-3.5% aluminum, about 0.4-2% titanium and about 2.5-5.5% iron, and preferably also about 0.002-1.50% zirconium. These alloys, due to a controlled silicon-chromium ratio of about 1:10 and the presence of titanium, and preferably also zirconium, are useful in making dental prosthetic applicances having improved strength, metal-ceramic bonding, and casting properties.
