Abstract: According to an embodiment of the present disclosure, an anodizable aluminum clad sheet may comprise a base material including a 7xxx-series aluminum alloy and a coat material including a 6xxx-series aluminum alloy or a 1xxx-series aluminum alloy disposed on one or both front and back surfaces of the base material, wherein the 7xxx-series aluminum alloy includes 4.0% to 8.0% of zinc (Zn) relative to a total weight of the aluminum clad sheet, 1.0% to 3.0% of magnesium (Mg) relative to the total weight of the aluminum clad sheet, and the rest being aluminum (Al) and at least one other impurity. According to an embodiment of the present disclosure, a method for manufacturing an aluminum clad sheet may enhance the adhesion strength of the clad sheet by employing thermal treatment after forming the clad sheet and may age-harden the clad sheet without deteriorating strength, thereby achieving superior surface and engineering properties.
