<P>PROBLEM TO BE SOLVED: To provide a metal wire rod containing iridium or an iridium alloy, in which oxidation consumption resistance is improved, and a method for producing the metal wire rod. <P>SOLUTION: The metal wire rod comprises the iridium or the iridium-containing alloy. The metal wire rod is biaxially oriented in the cross-section and exhibits ≥50% abundance ratio of the crystal texture that has the preferred orientation along the <100> direction in terms of crystal orientation. In the present invention, the orientation at the outer peripheral part on the outer side of 1/2 circle of the cross section, which constitutes the outer periphery of the wire rod, is important. Preferably, the abundance ratio of the crystal texture having the peripheral crystal orientation along the <100> direction, is ≥50% in this region. <P>COPYRIGHT: (C)2012,JPO&INPIT |
