A group of alloys exhibiting good corrosion resistance and with properties suitable for fabricating dental prostheses consist essentially of copper, nickel and tantalum. Copper and nickel comprise the major components, while tantalum is present in lesser quantities. Lithium and/or Ce, Si metal may be added in small amounts as a deoxidant. Minor amounts of elements such as aluminum, gallium, indium, silicon, titanium and cerium can be added to modify the physical properties of the alloys.
