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: &#x3e;2.0-7.0; Fe&#x3c;0.5; Cu&#x3c;1.0; Mn: 1.0-2.0; Mg&#x3c;0.5; Zn: 1.0-3.0; Cr&#x3c;0.25; Ni&#x3c;1.5; Ti&#x3c;0.25; Co&#x3c;1.5; V, In, Sn, Zr, Sc&#x3c;0.25 each; other elements &#x3c;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.'
