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
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.

The invention claimed is: 1. An aluminum alloy composite material for brazing, comprising: a core material; a brazing material formed of an Al--Si based aluminum alloy on one surface of the core material; and a cladding material formed on the other surface of the core material, each of the core material, the brazing material and the cladding material having a plate shape of roughly fixed thickness, the cladding material having a cladding ratio of 6 to 30% with respect to an entire thickness of the aluminum alloy composite material, the core material having a composition consisting essentially of 0.2 mass % or less of Mg, 0.02 to 0.3 mass % 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 a range of 2.0 mass % or less and a remainder of Al and unavoidable impurities, and the cladding material containing 2 to 9 mass % of Zn; at least one selected from the group consisting of 0.3 to 1.8 mass % of Mn and 0.04 to 1.2 mass % of Si; at least one selected from the group consisting of 0.02 to 0.25 mass % of Fe, 0.01 to 0.30 mass % of Cr, and 0.001 to 0.15 mass % of Cu; and a remainder of AI and unavoidable impurities. 2. The aluminum alloy composite material according to claim 1, wherein the cladding material contains 3 mass % or more of Zn and a Zn/Si mass ratio is 4 or more. 3. An aluminum alloy composite material for brazing, comprising: a core material; a brazing material formed of an Al--Si based aluminum alloy on one surface of the core material; and a cladding material formed on the other surface of the core material, each of the core material, the brazing material and the cladding material having a plate shape of roughly fixed thickness, the cladding material having a cladding ratio of 6 to 30% with respect to an entire thickness of the aluminum alloy composite material, the core material having a composition consisting essentially of 0.2 mass % or less of Mg, 0.02 to 0.3 mass % 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 a range of 2.0 mass % or less and a remainder of Al and unavoidable impurities, and the cladding material containing 2 to 9 mass % of Zn, 0.3 to 1.8 mass % of Mn, 0.5 to 1.2 mass % of Si, at least one selected from the group consisting of 0.02 to 0.25 mass % of Fe, 0.01 to 0.30 mass % of Cr, and 0.001 to 0.15 mass % of Cu, and a remainder of AI and unavoidable impurities, wherein in the cladding material a ratio of a sum of a total amount of Si in solid solution and a total amount of Si in precipitates having a grain size of less than 10 μm to said Si content of the cladding material is equal to or less than 0.5. 4. The aluminum alloy composite material according to claim 3, wherein the cladding material contains 3 mass % or more of Zn and a Zn/Si mass ratio is 4 or more.
