ELECTRICAL WIRE CONDUCTOR AND ELECTRICAL WIRE FOR AUTOMOBILE

摘要

Disclosed are an electrical wire conductor having excellent conductor strength and weldability, and an electrical wire for an automobile using the electrical wire conductor. Specifically disclosed is an electrical wire conductor which is configured from a copper alloy that contains Mg in an amount of 0.1-0.6% by mass and has an O2 concentration (mass ratio) of 50 ppm or less, with the balance made up of copper and unavoidable impurities. The copper alloy may additionally contain one or more elements selected from among Ag, In, Sr and Ca in a total amount of 0.0005-0.3% by mass. The copper alloy may also contain Sn in an amount of 0.2-0.75% by mass.
