Abstract
A clad material includes a core material, a first skin material covering one side of the core material, and a second skin material covering the other side of the core material. The clad material is brazed in a state in which the first and second skin materials overlap each other. The core material is made of an Al alloy containing Mn (0.6 to 1.5 mass %), Ti (0.05 to 0.25 mass %), Cu (less than 0.05 mass %), Zn (less than 0.05 mass %), Fe (0.2 mass % or less), and Si (0.45 mass % or less) (balance: Al and unavoidable impurities). The first skin material is made of an Al alloy containing Si (6.8 to 11.0 mass %) and Zn (0.05 mass % or less) (balance: Al and unavoidable impurities). The second skin material is made of an Al alloy containing Si (4.0 to 6.0 mass %) and Cu (0.5 to 1.0 mass %) (balance: Al and unavoidable impurities).
