Abstract
An aluminum-alloy-clad plate which includes a plurality of superposed aluminum alloy layers and which has undergone a diffusion heat treatment. Aluminum alloy layers having specific compositions are superposed so that any adjoining two of these differ in the content of Mg or Zn, and are subjected to a diffusion heat treatment to give a structure which has fine crystal grain diameters and Mg/Zn mutual diffusion regions and which has specific DSC properties. Thus, both higher strength and high formability are imparted.
