PURPOSE: Provided is a method for producing AlMn strips or sheets for producing components by soldering, thereby producing aluminum sheets having good suitability for soldering, high strength, particularly a high limit of elasticity(Rp0.2), and toughness even after soldering, as well as simultaneously good deformability and a high resistance to corrosion. CONSTITUTION: In a method for producing AlMn strips or sheets for producing components by soldering, a precursor material is produced from a melt which contains (in weight-percent) 0.3-1.2% Si, <=0.5% Fe, <=0.1% Cu, 1.0-1.8% Mn, <=0.3% Mg, 0.05-0.4% Cr+Zr, <=0.1% Zn, <=0.1% Ti, <=0.15% Sn, 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; the precursor material is preheated at a preheating temperature of less than 520 deg.C. over a dwell time of at most 12 hours; the preheated precursor material is hot rolled into a hot strip; the hot strip is cold rolled into a cold strip without intermediate annealing; and the cold band is finally subjected to an annealing treatment.
