Title:
ELECTRICAL WIRE CONDUCTOR FOR WIRING, METHOD FOR PRODUCING ELECTRICAL WIRE CONDUCTOR FOR WIRING, ELECTRICAL WIRE FOR WIRING, AND COPPER ALLOY WIRE
Document Type and Number:
WIPO Patent Application WO/2010/084989
Kind Code:
A1
Abstract:
Disclosed is an electrical wire conductor for wiring, which is obtained by bundling and twisting a plurality of copper alloy wires that have a composition containing 0.3-1.5% by mass of Cr with the balance made up of Cu and unavoidable impurities. The electrical wire conductor for wiring has a tensile strength of not less than 400 MPa but not more than 650 MPa, an elongation at break of not less than 7%, an electrical conductivity of not less than 65% IACS, a ratio of 0.2% proof stress to tensile strength of not less than 0.7 but not more than 0.95, and a work hardening coefficient of not less than 0.03 but not more than 0.17. Also disclosed are: a method for producing the electrical wire conductor for wiring; an electrical wire for wiring, which is obtained by providing the conductor with an insulation coating; and a copper alloy wire for the conductor.
