COPPER ALLOY WIRE, COPPER ALLOY STRANDED WIRE, COATED ELECTRIC WIRE, WIRE HARNESS AND MANUFACTURING METHOD OF COPPER ALLOY WIRE

摘要

A copper alloy wire for use as a conductor of an automotive electric wire includes in mass percent, Fe: 0.4% or more and 2.5% or less, Ti: 0.01% or more and 1.0% or less, one or more selected from the group consisting of Mg, Sn, Ag, Ni, In, Zn, Cr, Al and P: 0.01% or more and 2.0% or less in total, and the balance being Cu and unavoidable impurities. An O content in the copper alloy wire is preferably 20 ppm or less. A tensile strength of the copper alloy wire is preferably 450 MPa or more. An element wire elongation of the copper alloy wire is preferably 5% or more. An electrical conductivity of the copper alloy wire is preferably 62% IACS or more.
