ABSTRACT:
An Al—Si based brazing material is formed on one surface of a core material, and a cladding material is formed on the other surface of the core material with a cladding ratio of 6 to 30% with respect to an entire thickness thereof. The core material contains 0.2 mass % or less of Mg, 0.3 mass % or less of Cr, 0.2 mass % or less of Fe, 0.2 to 1.0 mass % of Cu, 0.05 to 1.3 mass % of Si, 0.3 to 1.8 mass % of Mn, and 0.02 to 0.3 mass % of Ti in such a manner that a total content of Cu and Si is in the range of 2.0 mass % or less. The cladding material contains 2 to 9 mass % of Zn, 0.3 to 1.8 mass % of Mn and/or 0.04 to 1.2 mass % of Si, and further contains 0.02 to 0.25 mass % of Fe, 0.01 to 0.30 mass % of Cr, 0.005 to 0.15 mass % of Mg, and/or 0.001 to 0.15 mass % of Cu.
