<p>Provided is a Ni-Cr-based brazing material having excellent wettability/spreadability and corrosion resistance, which can be brazed at a practicable temperature (1150°C or lower) when used for joining a ferritic stainless steel by brazing, and has a good brazing property, good joint strength and good corrosion resistance against a base material. The brazing material is characterized by comprising, in mass%, 45.0% or less of Fe, 10.0 to 35.0% of Cr, 4.0% or less of Si, 6.5 to 10.8% of P, Si and P in the total amount of 9.0 to 11.8%, 0.3 to 5.0% of Cu, 0.01 to 0.10% of at least one selected from Al, Ca, Y and a misch metal, and a remainder made up by Ni and unavoidable impurities, wherein the total amount of Cr and Fe is 6.5 times or less larger than the content of P. The brazing material may additionally contain, as elements that do not affect the properties of the brazing material, Co and/or Mo in an amount of 15.0% or less, W and/or Mn in an amount of 5.0% or less, and C, B and Ti in the total amount of 0.3% or less, wherein the total amount of Co, Mo, W, Mn, C, B and Ti is 15.0 mass% or less.</p> |
