摘要
The gold casting alloy, which does not contain Cu, has the compsn. 40-60% Au, 25-40% Ag, 5-20% Pd, 1-6% In and contains as grain refiner 0.01-0.1% Ge or Ti or Ce mischmetal. The grain refining alloy component has a m.pt. which is at least 700 degrees C lower than the m.pt. of known grain refining elements such as Ir and Ru. The alloy presents a saving in costs as it does not contain Pt.
