PROBLEM TO BE SOLVED: To provide an aluminum clad material for a heat exchanger exhibiting excellent corrosion resistance on the inside of a fluid passage of the heat exchanger manufactured by vacuum brazing. SOLUTION: In the aluminum clad material (1) for a heat exchanger, an intermediate material (12) and an inner coating material (13) are sequentially layered on one surface of a core material (11). The core material (11) is constructed of an aluminum alloy including 0.3-0.8 mass% of Cu, 0.2-0.6 mass% of Mg, and the balance Al with inevitable impurities. The intermediate material (12) is constructed of an aluminum alloy including 0.8-1.5 mass% of Mn, 0.8-3 mass% of Zn, and the balance Al with inevitable impurities. The inner coating material (13) is constructed of an aluminum alloy including 0.3-1.8 mass% of Mg and the balance Al with inevitable impurities. COPYRIGHT: (C)2012,JPO&INPIT |
