BRAZING PRODUCT

摘要

The invention relates to a brazing product, e.g. a brazing sheet product, having an aluminium layer (1) being made of an aluminium alloy comprising silicon in an amount in the range of 2 to 18% by weight, and a layer (2) comprising nickel on the outer surface of said aluminium layer (1) such that taken together said aluminium layer (1) and all layers exterior thereto form the filler metal for a brazing operation, characterised in that the filler metal has a composition containing at least one element with a smaller exchange current density for the Hydrogen Evolution Reaction ("HER") than nickel, and whereby the mol-ratio of Ni to such element(s) is in the range of 10:(0.3-30). The invention also relates to a method of manufacturing a brazed assembly using the brazing product, and to a brazed assembly comprising at least one component made of the brazing product.
