<p><P>PROBLEM TO BE SOLVED: To provide an aluminum alloy clad material for heat exchanger which has high strength after brazing, and has excellent pitting corrosion resistance and brazability. <P>SOLUTION: The aluminum alloy clad material 1a for heat exchanger comprises: a core material 2; a sacrificial material 3 formed at one face side of the core material 2; and a brazing filler metal 4 made of an Al-Si based alloy which is formed on the other face side of the core material 2. The sacrificial material 3 comprises, by mass, 0.001 to 0.01% Ca and 2.0 to 10.0% Zn, and the balance Al with inevitable impurities, and the core material 2 comprises, by mass, 0.1 to 1.5% Si, 0.3 to 2.0% Mn, 0.1 to 1.0% Cu and 0.02 to 0.30% Ti, and the balance Al with inevitable impurities. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
