Abstract
Official abstract text for this publication.
An aluminum alloy brazing sheet including a core material, a sacrificial material provided on one surface of the core material, a brazing filler material provided on the other surface side of the core material, and an intermediate layer provided between the core material and the brazing filler material. The core material contains Si: 0.30 to 1.00 mass %, Mn: 0.50 to 2.00 mass %, Cu: 0.60 to 1.20 mass %, Mg: 0.05 to 0.80 mass %, and Al. The sacrificial material contains Si: 0.10 to 1.20 mass %, Zn: 2.00 to 7.00 mass %, Mn: 0.40 mass % or less, and Al. The intermediate layer contains Si: 0.05 to 1.20 mass %, Mn: 0.50 to 2.00 mass %, Cu: 0.10 to 1.20 mass %, and Al.
