Abstract: The present invention provides a method for producing AlMn strip or sheet for making components by brazing, as well as the products obtained by said method. In particular this method is related to fin materials used in heat exchangers. The fins can be delivered with or without a cladding depending on application. Rolling slabs are produced from a melt which contains 0.3-1.5% Si, ?0.5% Fe, ?0.3% Cu, 1.0-2.0% Mn, ?0.5% Mg, ?4.0% Zn, ?0.3% each of elements from group IVb, Vb, or VIb elements, and unavoidable impurity elements, as well as aluminum as the remainder in which the rolling slabs prior to hot rolling are preheated at a preheating temperature of less than 550° C., preferably between 400 and 520° C., more preferably between 450 and 520° C. to control the number and size of dispersoid particles, and the preheated rolling slab is hot rolled into a hot strip. The strip is thereafter cold rolled into a strip with a total reduction of at least 90%, and the cold rolled strip is heat treated to obtain a 0.
