Patent ID: 8247084

Claim:
An aluminum alloy brazing sheet comprising: a core material containing Si: 0.1-1.0 mass %, Cu: 0.5-1.2 mass %, and Mn: 0.5-2.0 mass %, the balance being Al and inevitable impurities; a sacrificial anode material disposed on one face side of the core material and containing Si: exceeding 0.2 mass % and 0.8 mass % or below, Zn: exceeding 3.0 mass % and 5.0% or below, and Mg: 1.0-4.5 mass %, the balance being Al and inevitable impurities; and a brazing filler material disposed on the other face side of the core material and formed of an aluminum alloy, wherein an area fraction of Zn—Mg-based intermetallic compounds with 2.0 μm or above particle size on a surface of the sacrificial anode material is 1.0% or below.
