摘要
Production of AlMn bands or sheets used in the manufacture of building components by soldering comprises producing a pre-material from a melt containing 0.3-1.2 wt.% Si, 0.5 wt.% Fe, 0.1 wt.% Cu, 1.0-1.8 wt.% Mn, 0.3 wt.% Mg, 0.05-0.4 wt.% Cr + Zr, 0.1 wt.% Zn, 0.1 wt.% Ti, and 0.15 wt.% Sn, unavoidable impurities whose individual contents are a maximum of 0.05% and whose sum is a maximum of 0.15 wt.%, and a balance of aluminum. The pre-material is heated to less than 520 degrees C for a maximum of 12 h, hot-rolled at at least 250 degrees C to form a hot band, and cold-rolled to form a cold band without intermediate annealing. An Independent claim is also included for an AlMn band or sheet produced by the above process. Preferred Features: The minimum Si content is 0.5, preferably 0.75 wt.% and the maximum Si content is 1.0 wt.%. The maximum Fe content is 0.3 wt.%. The maximum Cu content is 0.05 wt.%. The Mn content is 1.3-1.5 wt.%. The maximum Mg content is 0.1 wt.%. The Cr content is 0.1-0.2 wt.%. The maximum Zr content is 0.05 wt.%. The maximum Zn content is 0.05 wt.%. The maximum Ti content is 0.05 wt.%.
