Abstract (en)
Provided is a copper alloy wire rod superior in the balance of the strength, the electric conductivity and the drawability. A copper alloy wire rod comprises an alloy composition including 1.0% by mass or more and 6.0% by mass or less of Ag, a remainder being Cu and inevitable impurities, in which, for a peak intensity I(111) of 111 diffraction and a peak intensity I(220) of 220 diffraction obtained by X-ray diffraction analysis of a surface, a peak intensity ratio of the peak intensity I(111) relative to the peak intensity I(220) (the peak intensity I(111)/the peak intensity I(220)) is 0.50 or more and 1.50 or less.
