Abstract (en)
[origin: WO2021140296A1] Disclosed is a method for manufacturing a multilayer strip or sheet, comprising the consecutive steps of: - casting a brazing aluminum alloy in the form of a cast plate; - sawing the cast plate to obtain sawn brazing alloy layers; - assembling a core aluminum alloy layer with at least one sawn brazing aluminum alloy layer to obtain a multilayer assembly; - preheating the multilayer assembly; - hot-rolling the multilayer assembly to obtain a multilayer strip or sheet, the first hot-rolling pass inducing a reduction in the thickness of the multilayer assembly greater than or equal to 0.5% of the thickness of the multilayer assembly before said hot-rolling pass.
