摘要： The present invention is a metallic wire rod comprising iridium or an iridium-containing alloy and, the wire rod has in the cross section thereof biaxial crystal orientation of 50% or more of abundance proportion of textures in which crystallographic orientation has preferred orientation to direction. In the present invention, crystal orientation in the outer periphery from semicircle of the cross section which is the periphery of the wire rod is important, and in this zone, abundance proportion of textures in which crystallographic orientation has preferred orientation to direction is preferably not less than 50%.

摘要： A material for a plug electrode having not only excellent oxidation wear resistance but also excellent spark wear, and also having adequately-considered discharge properties in use is provided. The present invention relates to a material for a plug electrode, comprising 5% by mass or more and 30% by mass or less of Cu, 0.1% by mass or more and 15% by mass or less of Ir, with the balance being Pt. Alloying by combining two metals of Cu and Ir can reduce discharge voltages and improve durability against spark wear. With addition of only one of them, the effect of improving spark wear properties is poor and the effect of reducing discharge voltages cannot be expected.
