Provided is a low-cost Cu-added Ni-Cr-Fe-based alloy brazing material which has a low melting temperature, excellent corrosion resistance and excellent strength, and which is used for the production of a heat exchanger that is formed of stainless steel, or the like. This Ni-Cr-Fe-based alloy brazing material is composed of 15-30% by mass of Cr, 15-30% by mass of Fe, 2.1-7.5% by mass of Cu, 3-12% by mass of P, 0-8% by mass of Si, and the balance made up of Ni and unavoidable impurities. The total content of Cr and Fe is 30-54% by mass, and the total content of P and Si is 7-14% by mass. |
