Abstract

See full text

A method of manufacturing a Cu alloy conductor includes the steps of:

    adding and dissolving In of 0.1-0.7 weight % to a Cu matrix containing oxygen of 0.001-0.1 weight % (10-1000 weight ppm) to form a molten Cu alloy,performing a continuous casting with the molten Cu alloy, rapidly quenching a casting material to a temperature by at least 15° C. or more lower than a melting point of molten Cu alloy,controlling the casting material at a temperature equal to or lower than 900° C., andperforming a plurality of hot rolling processes to the casting material such that a temperature of a final hot rolling is within a range of from 500 to 600° C. to form the rolled material.
