A brazing clad material is a composite material that comprises a base
material and a brazing material layer formed integrally on the base
material. The brazing material layer has a Ni or Ni alloy layer, a Ti or
Ti alloy layer and a Fe--Ni alloy layer that are sequentially stacked in
this order on the base material. The brazing material layer has a Fe
concentration of 25 to 40 wt % in the entire brazing material layer. The
brazing material layer satisfies a ratio of W1/W2 to be 0.56 to 0.66,
where W1 is a weight of Ni contained in the entire brazing material layer
and W2 is a total weight of Ni and Ti contained in the entire brazing
material layer.
