Disclosed is an alloy that is a combination by weight percent of 78 to 84 percent nickel, 11 to 15 percent chromium, 3 to 5 percent vanadium, and 1 to 2 percent beryllium. Any balance of other elements make up less than 7 percent with aluminum, manganese, silicon, tin, lanthanum, cerium, praseodymium, neodymium, samarium, gadolinium, molybdenum, niobium, tantalum, tungsten, titanium, iron, boron, and carbon specifically disclosed. The alloy is, in particular, a dental casting alloy or dental veneering alloy, and dental prostheses containing the alloy is a feature of the disclosure.

Dental prostheses alloy

A nickel base casting alloy containing 10 to 25 percent chromium, 3 to 8 percent manganese, 3 to 10 percent niobium, 0 to 3.5 percent aluminum, 0.5 to 2.0 percent beryllium which exhibits lower melting characteristics allowing enhanced compatibility to gypsum bonded investments.
