Abstract:
1. A strip, wire or reshaped part, comprising an alloy of a base metal selected from platinum, palladium or a mixture of platinum and palladium and at least one oxide generator which forms a volatile oxide that is more volatile than other alloy components, the alloy being hardened by oxide dispersion and the at least one oxide generator being selected from 0.3 to 50% by weight of iridium, 0.3 to 30% by weight of ruthenium, 0.3 to 20% by weight of rhenium, 0.3 to 10% by weight of tungsten, and 0.3 to 10% by weight of molybdenum, wherein the platinum and/or palladium comprise at least 50% by weight of the alloy and the at least one oxide generator comprises in total 3% to 35% by weight of the alloy, and wherein a cross-section of the strip, wire or reshaped part has a peripheral zone amounting to 0.1 to 5% of a thickness of the strip, wire or reshaped part, the at least one oxide generator being depleted by at least one quarter in the peripheral zone.
