Beschreibung
Zusammenfassung:	The invention relates to an aluminium composite material having at least one core layer of an aluminium core alloy and at least one corrosion protection layer arranged on the core layer. The aluminium composite material has improved corrosion resistance, in particular avoids coarse detachments under corrosive conditions, through use of a corrosion protection layer with the following composition in wt %: Si≤0.10%, Fe≤0.6%, Cu≤0.2%, 0.9%≤Mn≤1.2%, Mg≤0.10%, Cr≤0.3%, Zn≤0.1%, Ti≤0.1%, the rest Al and unavoidable impurities, individually at most 0.05%, in total at most 0.15%. The invention furthermore relates to a method for producing an aluminium composite material, a use as well as a heat exchanger or a component of a heat exchanger.
