Brazing sheet product and method of its manufacture
First Claim
1. A brazing sheet product comprising a core metal sheet, on at least one side of said 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 outer surface of said 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).
