ABSTRACT:
A metal composite material having an aluminium surface layer firmly bonded on a substrate material consisting of a metal other than aluminium is produced by cold pressure bonding the metal substrate material to an aluminium foil superimposed thereon, subjecting the bonded material to a diffusion heat treatment at a temperature lower than the melting points of both the aluminium foil and the substrate material and, if desired, hot pressure bonding the bonded material to an aluminium material superimposed on the aluminium foil layer of the bonded material at a temperature lower than the melting point but not lower than the recrystallizing point of the aluminium material.
