PURPOSE: To obtain a Pd-gold alloy for baking dental ceramic material excellent in mechanical and physico-chemical properties by adding specific percentage of Ga, Sn, Fe and Ir to a base alloy consisting of specific percentage of Pd, Au, Sb and In.
CONSTITUTION: The base alloy having a compounding weight ratio consisting of 30W75% Pd, 10W60% Au, 1W25% Sb and 0.5W15% In is prepared, to which at least one kind among additive elements having a compounding weight ratio consisting of 0.01W10% Ga, 0.01W10% Sn, 0.1W5% Fe and 0.01W1% Ir is added. In this way, the Pd-gold alloy most satisfactory in respects of physical, mechanical and chemical properties, sanitation and aesthetic appreciation required of artificial teeth etc., for dental treatment can be manufactured.
