ABSTRACT:
Disclosed is a brazing sheet product comprising a core metal sheet, on at least one side of the core sheet a clad layer of an aluminium brazing alloy comprising silicon in an amount in the range of 4 to 14% by weight, and further comprising on at least one outersurface of the clad layer a coated layer of iron-X alloy, wherein X is selected from one or more members of the group consisting of tin, zinc, manganese, and copper, and such that the clad layer and all layers exterior thereto form a metal filler for a brazing operation and having a composition with the proviso that the mol-ratio of Fe:X is in the range of 10:(0.3 to 6). The invention also relates to a method of manufacturing such a brazing product, and to a brazed assembly comprising at least one component made of this brazing product.
