The present invention concerns a high strength aluminium alloy brazing sheet, comprising an Al-Cu core layer and at least one clad layer, said core layer comprising essentially the following composition (in weight percent): Cu: 1.2 - 4.0, Mn: 0.06 - 1.5, Mg: 0.06 - 1.5, Si: up to 0.5, Zn: :<= 0.4, Zr: :<= 0.25, Fe: :<= 0.5, Ti: :<= 0.25, Cr: :<= 0.25; V:<= 0.25; the balance essentially aluminium and impurities, said clad layer comprising an Al-Si based filler alloy and being applied on at least one side of the core layer. The invention further relates to a brazed assembly comprising said brazing sheet and to) the use of said brazing sheet for a brazing application such as a heat exchanger. |
