COMPOSITE MATERIAL FOR ELECTROMAGNETIC INDUCTION HEATING AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To provide a composite material for electromagnetic induction heating, in which the junction strength between a magnetic metal plate and an aluminum plate is remarkably improved and to provide its manufacturing method. SOLUTION: This composite material comprises a magnetic metal plate and an aluminum plate joined together via metal plating layers provided on one side of each. Each metal plating layer comprises a nickel plating bed layer and a copper plating layer provided thereon. Also, the nickel plating bed layer is formed on one side of each of the magnetic metal plate and the aluminum plate, and after the copper plating layer is formed thereon, the magnetic metal plate and the aluminum plate are joined together via the copper plating layers.
