Abstract
A surface metal plate 2 made of aluminium or aluminium alloy is overlayed upon a backing metal plate 1 and integrally bonded by cold rolling bonding of a rolling machine 30. After that, the thus obtained composite metal plate 3 is annealed, so that the bonding strength between a surface metal layer 1a having a thickness of 2 to 8 mm and a backing metal layer 2a is enhanced.
