Abstract
An alloy composition for dental use containing, by weight, aluminum 0-3.0%, cobalt 0-20.0%, chromium 10.0-20.0%, manganese 0-1.5%, molybdenum 6.0-18.0%, nickel 58.5-77.0% and silicon 0-2.0%. The alloy retains the corrosion resistance properties found in nickel-chromium base alloys while having reduced yield strength typical of gold alloys thereby resulting in greater ease of grinding, polishing and manipulation. The alloy finds use as a porcelain substrate alloy and also as a crown and bridge or partial denture alloy.
