Abstract
A process for producing a fcc metal consisting of copper having random orientations comprising cross rolling which is performed to achieve a total draft of at least 20% with the rolling axis being offset at 15.degree. or more in each pass to a total offset of at least 90.degree., and subsequent full annealing which is accompanied by recrystallization, the fcc metal satisfying the following relationships: I.sub.(200) /I.sub.(111).ltoreq.2.3 and I.sub.(220) /I.sub.(111).ltoreq.1.0, where I.sub.(111), I.sub.(200) and I.sub.(220) are the integral intensities of the (111), (200) and (220) faces, respectively, of crystal faces as measured by X-ray diffractiometry.
