The invention provides an alloy useful particularly in dentistry. The alloy of the invention in its broadest aspect contains from about 0.05 to about 8% by weight of indium and from about 8 to about 20% by weight of iridium, the balance essentially being platinum. Preferably, however, the allow consists essentially of platinum, iridium and indium, and contains from about 0.05 to about 8% by weight of indium, with the weight ratio of platinum to iridium being from about 84 to about 86:15.
