  • Heat-resistant Ir alloy wire
    Patent number: 11486024
    Abstract: Provided is an Ir alloy wire, which is further improved in oxidation wear resistance while ensuring a Vickers hardness. The Ir alloy wire includes: 5 mass % to 30 mass % of Rh; and 0.5 mass % to 5 mass % of Ta, wherein an average value A for an aspect ratio (crystal grain length/crystal grain width) of a structure of the alloy wire in a range of a depth of 0.05 mm or less from a surface of the alloy wire satisfies 1?A<6.
