摘要
There is provided a Ni-Cr-Fe-based alloy brazing filler material to which Cu is added, and which has a low melting temperature, and is inexpensive and excellent in corrosion resistance and in strength, for use in manufacture of stainless-steel heat exchangers or the like, specifically, a Ni-Cr-Fe-based alloy brazing filler material, including, in mass%, Cr: 15 to 30%; Fe: 15 to 30%; Cu: 2.1 to 7.5%; P: 3 to 12%; and Si: 0 to 8%; and the balance being Ni and unavoidable impurities, wherein the total content of Cr and Fe is 30 to 54%, and the total content of P and Si is 7 to 14%.
