PROBLEM TO BE SOLVED: To provide an inexpensive Ni-Cr-Fe-based alloy brazing filler metal with added Cu, which is used for manufacture of a stainless steel heat exchanger and the like, which makes a melting temperature low, and which is excellent in corrosion resistance and strength.SOLUTION: An Ni-Cr-Fe-based alloy brazing filler metal with added Cu includes 15-30 mass% Cr, 15-30 mass% Fe, 2.1-7.5 mass% Cu, 3-12 mass% P, and 0-8 mass% Si. The Ni-Cr-Fe-based alloy brazing filler metal with the added Cu comprises the balance Ni and inevitable impurities. The total mass of the Cr and the Fe is in the range of 30-54 mass%, and the total mass of the P and the Si is in the range of 7-14 mass%. |
