The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: This method for producing an aluminum alloy clad material for press molding having a core material and a first skin material and second skin material joined to the respective sides of the core material so as to sandwich the core material involves: a step A for preparing a first aluminum alloy by using scrapped aluminum alloy clad material from an automobile heat exchanger containing Si, Fe, Cu, Mn, Mg, Cr, Zn, and Ti as additive elements; a step B for preparing a second aluminum alloy in which the content ratios of at least Si and Cu are smaller than those in the first aluminum alloy; a step C for forming a plate material for the core material by using the first aluminum alloy; a step D for forming a plate material for the first skin material and a plate material for the second skin material independently by using the second aluminum alloy; and a step E for rolling the plate material for the first skin material and the plate material for the second skin material in a state where the plate material for the first skin material and the plate material for the second skin material are arranged so as to sandwich the plate material for the core material.
