Abstract

A castable dental alloy suitable for bonding with dental porcelain and having a stable yellow-gold colour which is retained after porcelain is fired on the cast alloy is provided by the present invention. The alloy comprises about 83 to 87% gold, 7 to 12% platinum, 1.5 to 3% rhodium, no more than about 1% copper, said %'s being by weight, and further elements for grain refining and formation of bonding oxides, the weight ratio of rhodium to copper in the alloy being in the range of 3 to 15. The further elements consist of: Ag less than 4% In less than 2% Sn less than 1.5% Ir less than 1% Fe less than 0.5% Ru less than 1% Rh less than 1% e
