Abstract: An amorphously solidifying noble metal alloy has the following composition of AaBbCc, wherein: A represents at least one noble metal from a group of platinum and palladium; B represents at least one element from a group of Al, Au, Ag and Cu; and C represents at least one element from a group of Ga and Ge. The mass fraction a lies in a region of 45-60 mass percent. The mass fraction b lies in the region of 39-55 mass percent. The mass fraction c lies in the region of 0-13 mass percent. Where platinum and palladium are both present, the amorphous noble metal alloy does not have aluminum as the sole alloy component from group B. The above mass fractions a, b and c, aside from typical admixtures, impurities and alloy tolerances, add up to 100 mass percent.
