The invention relates to an amorphously solidifying noble metal alloy, characterised by the following composition: AaBbCc, wherein: - A represents at least one noble metal from a group consisting of platinum and palladium; - B represents at least one element from a group consisting of Al, Au, Ag and Cu; - C represents at least one element from a group consisting of Ga and Ge; the mass fraction a lies in a region of 45-60 mass percent, preferably in the region of 45-59 mass percent, most preferably in the region of 48 to 54 mass percent, the mass fraction b lies in the region of 39-55 mass percent, preferably in the region of 39-49 mass percent, most preferably in the region of 40 to 47 mass percent, and the mass fraction c lies in the region of 0-13 mass percent, preferably in the region of 1-13 mass percent, most preferably in the region of 2 to 10 mass percent and especially preferably in the region of 2 to 5 mass percent; in a case where platinum and palladium are both present, the amorphous noble metal alloy preferably does not have aluminum as the sole alloy component from group B; and wherein the above mass fractions a, b and c, aside from typical admixtures, impurities and alloy tolerances, add up to 100 mass percent. |
