Abstract
A sacrificial material on one surface of a core material, a Al brazing material containing Si: 6.0% to 14.0%, Mg: 0.05% to 1.5%, Bi: 0.05% to 0.25%, Sr: 0.0001% to 0.1%, and Al balance and satisfying (Bi+Mg)×Sr≤0.1 is disposed on the other surface, Mg—Bi-based compounds of the brazing material with a diameter of 0.1-5.0 μm are more than 20 per 10,000-μmand the Mg—Bi-based compounds with a diameter of 5.0 μm or more are less than 2 before brazing, the core material contains Mn: 1.0% to 1.7%, Si: 0.2% to 1.0%, Fe: 0.1% to 0.5%, Cu: 0.08% to 1.0%, Mg: 0.1% to 0.7%, and Al balance, the sacrificial material contains Zn: 0.5% to 6.0% and Mg of which a content is limited to 0.1% or less, and a Mg concentration on a surface of the sacrificial material after brazing is 0.15% or less.
