The present invention related to a method for producing AlMn strips or sheets for producing components by soldering, wherein a precursor material is produced from a melt which contains (in weight-percent) Si: 0.3 - 1.2 %, Fe: .ltoreq. 0.5 %, Cu: .ltoreq. 0.1 %, Mn: 1.0 - 1.8 %, Mg: .ltoreq. 0.3 %, Cr + Zr: 0.05 - 0.4 %, Zn: .ltoreq. 0.1 %, Ti: .ltoreq. 0.1 %, Sn: .ltoreq. 0.15%, and unavoidable companion elements, whose individual amounts are at most 0.05 % and whose sum is at most 0.15 %, as well as aluminum as the remainder, wherein the precursor material is preheated at a preheating temperature of less than 520 .degree.C over a dwell time of at most l2 hours, wherein the preheated precursor material is hot rolled into a hot strip using a final hot rolling temperature of at least 250 .degree.C, wherein the hot strip is cold rolled into a cold strip without intermediate annealing.
