Abstract: An aluminum strip for a component, in particular a brazing component, in particular a tube or a disk, includes a profile having a brazing connection, wherein in at least one area, in particular in the area of the brazing connection: a first part of the strip thickness is taken up by a core layer of a first aluminum alloy; at least a second part of the strip thickness is taken up by at least one plating layer of a second aluminum alloy, wherein the first and the second aluminum alloy are configured to form a “brown band” layer during a brazing process; and at least a third part of the strip thickness is taken up by at least one “brown band” layer that is formed out of the first and the second aluminum alloy during the brazing process, and wherein a strip thickness of the aluminum strip is less than 500 ?m and a thickness of the core layer and/or a thickness of the plating layer is configured such that after the brazing process at least 5% of the strip thickness that is taken up by the first aluminum alloy of t
