CA 2721747

The invention relates to a sandwich material for brazing comprising a core layer of a first aluminum alloy and a barrier layer of a second aluminum alloy characterized by that: the first alloy, constituting the core layer contains (in weight %):0.8-2% Mn,<= 1.0% Mg,0.3 -1.5% Si,<= 0.3% Ti,<= 0.3% Cr,<= 0.3% Zr,<= 1.3% Cu,<= 0.5% Zn,<= 0.2% In,<= 0.1% Sn and <= 0.7% (Fe + Ni), the balance consisting of Al and <= 0.05% of each of the unavoidable impurities, and that the second alloy, constituting the barrier layer contains (in weight %): <= 0.2% Mn + Cr, <= 1.0% Mg, <= 1.5% Si, <= 0.3% Ti, <= 0.2 % Zr, <= 0.3% Cu, <= 0.5% Zn, <= 0.2% In, <= 0.1 % Sn and <= 1.5% (Fe + Ni), the balance consisting of Al and <= 0.05% of each of the unavoidable impurities, The invention also concerns a method for the manufacture of the sandwich material, a brazed product, such as a heat exchanger comprising the sandwich material and the use of the brazed product at high and low temperatures.

L'invention porte sur un matériau en sandwich pour le brasage comprenant une couche de cur constituée d'un premier alliage de l'aluminium et une couche barrière constituée d'un second alliage de l'aluminium, caractérisé par le fait que : le premier alliage, constituant la couche de cur, contient (en % en poids) : 0,8-2 % de Mn, = 1,0 % de Mg, 0,3-1,5 % de Si, = 0,3 % de Ti, = 0,3 % de Cr, = 0,3 % de Zr, = 1,3 % de Cu, = 0,5 % de Zn, = 0,2 % d'In, = 0,1 % de Sn et = 0,7 % de (Fe + Ni), le reste étant constitué d'Al et de = 0,05 % de chacune des impuretés inévitables, et par le fait que le second alliage, constituant la couche barrière, contient (en % en poids) : = 0,2 % de Mn + Cr, = 1,0 % de Mg, = 1,5 % de Si, = 0,3 % de Ti, = 0,2 % de Zr, = 0,3 % de Cu, = 0,5 % de Zn, = 0,2 % d'In, = 0,1 % de Sn et = 1,5 % de (Fe + Ni), le reste étant constitué d'Al et de = 0,05 % de chacune des impuretés inévitables. L'invention porte également sur un procédé pour la fabrication du matériau en sandwich, sur un produit brasé, tel qu'un échangeur de chaleur comprenant le matériau en sandwich, et sur l'utilisation du produit brasé à des températures élevées et basses.
