Abstract: A multi layered aluminium alloy brazing sheet consisting of: a core material that on either one or both sides has an intermediate layer consisting of an Al-Si braze alloy interposed between the core and a thin covering layer on top of the intermediate layer, where the said core material and the covering layer has a higher melting temperature than the Al-, braze alloy, the covering layer containing Bi 0.01 to 1.0wt-%, Mg =0.01wt-%, Mn =1.0 wt-%, Cu=1.2 wt-%,Fe =1.0 wt-%, Si =4.0wt-%,Ti =0.1 wt-%, Zr,Cr, V and/or Sc in total =0.2%, and unavoidable impurities each in amounts less than 0.05wt-%,and a total impurity content of less than 0.2wt-%, the balance consisting of aluminium; and a heat exchanger comprising the alloy brazing sheet.
