Leveling process for aluminum alloy asymmetric composite board

The invention discloses a leveling processing for an aluminum alloy asymmetric composite board. The leveling process comprises the following steps: a, putting the aluminum alloy asymmetric composite board into a roller hearth furnace for carrying out solution and quenching treatment; b, putting the board subjected to quenching treatment into a board stretcher for carrying out normative plastic tensile deformation, and providing smaller than 1.0 percent of stretching quantity according to the actual flatness condition of the board; c, putting the stretched board into a hydraulic leveler for carrying out leveling operation. The leveling processing for the aluminum alloy asymmetric composite board, disclosed by the invention, has the advantages that the treated aluminum alloy asymmetric composite board MX52 board retains original performance of the aluminum alloy asymmetric composite board, and also obtains excellent processing performance; the integral flatness of the composite board isimproved while buckling d
