Abstract

A gold alloy consists of 0,5-4 per cent of cobalt, 0,5-1 per cent of chromium, copper and silver in the ratio of 1,2 : 1-1\15 : 1, and sufficient gold, e.g. 65 or 75 per cent, to comply with the required standard. The alloy after tempering may be subsequently annealed by heating for 4 hours at 200 DEG C.
