Abstract
A brazing sheet made up of a core sheet made of aluminum alloy covered on at least one side with a layer of cladding forming a sacrificial anode. The layer of cladding is formed of an aluminum alloy of chemical composition, in % by weight: Si: >2.0-7.0; Fe<0.5; Cu<1.0; Mn: 1.0-2.0; Mg<0.5; Zn: 1.0-3.0; Cr<0.25; Ni<1.5; Ti<0.25; Co<1.5; V, In, Sn, Zr, Sc<0.25 each; other elements <0.05 each and 0.15 in total. A heat exchanger tube may be produced by folding and brazing from the brazing sheet, where the layer of cladding forms a sacrificial anode constituting the lining of the tube or 'inner-liner.'
