MANUFACTURING METHOD FOR COPPER-CLAD ALUMINUM WIRE AND COPPER-CLAD ALUMINUM WIRE

摘要

PROBLEM TO BE SOLVED: To provide a CA-wire manufacturing method which is excellent in productivity and is capable of more firmly adhering a Cu coating and an Al wire to each other when manufacturing a CA wire by a sand-blasting processing method.;SOLUTION: The CA-wire manufacturing method is configured as follows. The surface of an Al wire 1 is subjected to sand-blasting processing by using Cu fine powder 3. Then, the abutting parts of a Cu tape are continuously welded while longitudinally attaching the Cu tape to the Al wire. Diameter-reduction processing is executed so as to adhere the Cu tape to the Al wire, thereby forming a CA composite wire. The obtained CA composite wire is subjected to wire drawing processing until it reaches the target wire diameter.;COPYRIGHT: (C)2010,JPO&INPIT
