OXYGEN-FREE COPPER ROUGH DRAWING WIRE FOR WINDING AND METHOD FOR PRODUCING OXYGEN-FREE COPPER ROUGH DRAWING WIRE FOR WINDING

摘要

PROBLEM TO BE SOLVED: To provide an oxygen-free copper rough drawing wire for windings in which surface quality after cold working such as drawing is satisfactory, and the generation of a blister defect or the like can be suppressed, and to provide a method for producing an oxygen-free copper rough drawing wire for windings.;SOLUTION: The oxygen-free copper rough drawing wire for windings used as a material for producing windings has a composition comprising, by parts per million mass, at least one selected from Zr and Mg by 3 to 20 ppm, and in which the content of O is regulated to ≤10 ppm, and the balance Cu with inevitable impurities.;COPYRIGHT: (C)2010,JPO&INPIT
