Claim Text:
1. A copper alloy, comprising: by mass, Ni in a content of from 1.0% to 3.6%; Si in a content of from 0.2% to 1.0%; Sn in a content of from 0.05% to 3.0%; Zn in a content of from 0.05% to 3.0%; and copper, wherein: the copper alloy has an average grain size of 25 μm or less; the copper alloy comprises a texture having an average area percentage of cube orientation {001}<100> of from 20% to 60% and having an average total area percentage of specific three orientations of from 20% to 50% as measured by scanning electron microscope-electron back-scattering pattern analysis (SEM-EBSP) with the three orientations being brass orientation {011}<211>, S orientation {123}<634>, and copper orientation {112}<111>; and the copper alloy has a kernel average misorientation (KAM) value of from 1.00 to 3.00.
