ABSTRACT:
An electrically conductive copper alloy material for such as electric wires is disclosed whose grain size number is adjusted to be not less than 7 (JIS G 0551) which corresponds substantially to ASTM E112 by making an ingot of a copper alloy containing Cr and/or Zr, hot-working it to a wire of suitable diameter, and repeatedly annealing and cold-working it. A method for manufacturing such material is also disclosed.
