Copper alloy wire, copper alloy stranded wire, electric wire, terminal-fitted electric wire, and method of manufacturing copper alloy wire

Abstract

Provided are: a copper alloy wire having an excellent electrical conductivity, a high strength, and an excellent elongation; a copper alloy stranded wire including the copper alloy wire; an electric wire including the copper alloy wire or the copper alloy stranded wire as a conductor; a terminal-fitted electric wire including the aforementioned electric wire; and a method of manufacturing a copper alloy wire. The copper alloy wire has a composition including: not less than 0.2% by mass and not more than 1% by mass of Mg; not less than 0.02% by mass and not more than 0.1% by mass of P; and the balance including Cu and inevitable impurities. The copper alloy wire has an electrical conductivity of not less than 60% IACS, a tensile strength of not less than 400 MPa, and an elongation at breakage of not less than 5%.
