Aluminum alloy brazing sheet and manufacturing method thereof
An aluminum alloy brazing sheet is formed of a brazing material, an intermediate material, a core material, and a brazing material. The intermediate material contains Mg of 0.40 to 6.00 mass %, and has total of contents of Mn, Cr, and Zr being 0.10 mass % or more. The core material contains Mg of 0....

| description | An aluminum alloy brazing sheet is formed of a brazing material, an intermediate material, a core material, and a brazing material. The intermediate material contains Mg of 0.40 to 6.00 mass %, and has total of contents of Mn, Cr, and Zr being 0.10 mass % or more. The core material contains Mg of 0.20 to 2.00 mass % and one or two or more of Mn of 1.80 mass % or less, Si of 1.50 mass % or less, Fe of 1.00 mass % or less, Cu of 1.20 mass % or less, Ti of 0.30 mass % or less, Zr of 0.30 mass % or less, and Cr of 0.30 mass % or less. Each of the core material and the intermediate material has a grain size of 20 to 300 μm, and each of the brazing materials contain Si of 4.00 to 13.00 mass %. |
