Copper Alloy Plate, Electronic Component For Passage Of Electricity, And Electronic Component For Heat Dissipation

Abstract

Provided is a copper alloy plate consisting of 0.1 to 0.6% by mass of Cr, and from 0.01 to 0.30% by mass in total of one or more of Zr and Ti, the balance being copper and unavoidable impurities. In the copper alloy plate, a difference between a Schmidt factor when tensile stress is applied in a direction parallel to a rolling parallel direction (RD) with respect to a peak orientation of integrated intensity in an inverse pole figure in the RD, as obtained from XRD measurement, and a Schmidt factor when tensile stress is applied in a direction parallel to a rolling perpendicular direction (TD) with respect to a peak orientation of integrated intensity in an inverse pole figure in the TD, as obtained from XRD measurement, is 0.05 or less.

Dependencies are inferred from the claim text.
