ABSTRACT:
A novel laminated composite material of gold-colored appearance especially suited for, but not limited to, coinage applications has a ferromagnetic core located between sheathing layers of a Cu-Al or Cu-Ni-Al alloy and separated therefrom by layers of copper. Alternative methods involving hot and/or cold rolling techniques are provided for the production of the novel laminates.
