ABSTRACT:
A yellow dental alloy containing a colored intermetallic compound of palladium and indium as 15-85% by weight of the alloy and at least 10% by weight of silver and as desired gold 0-30%, copper 0-45% and silver 10-50%. This alloy exhibits a pale yellow gold color which it derives from the interaction of two white colored metals--palladium and indium. Various alloying additions are specified to improve castability, ductility, strength, hardness, tarnish and corrosion resistance.
