Abstract (en)
[origin: WO2005118899A1] The invention relates to a process for producing an Al-Mn alloy sheet with improved liquid film migration resistance when used as core alloy in brazing sheet, comprising the steps of: casting an ingot having a composition comprising (in weight percent): 0.5 < Mn <= 1.7 0.06<Cu<=1.5 Si <= 1.3 Mg <= 0.25 Ti < 0.2 Zn <= 2.0 Fe <= 0.5 at least one element of the group of elements consisting of 0.05 < Zr <=0.25 and 0.05 < Cr<=0.25 other elements < 0.05 each and total <0.20, balance Al. homogenisation and preheat hot rolling . cold rolling (including intermediate anneals whenever required), and wherein the homogenisation temperature is at least 450 °C for a duration of at least 1 hour followed by an air cooling at a rate of at least 20 °C/h and wherein the pre-heat temperature is at least 400 °C for at least 0.5 hour.
