摘要:
Disclosed is an aluminum alloy brazing sheet for heat exchangers, which has high strength after brazing, high corrosion resistance and excellent brazability. Specifically disclosed is an aluminum alloy brazing sheet (1a) for heat exchangers comprising a core member (2), a sacrificial member (3) formed on one side of the core member (2), and a brazing filler metal (4) formed on the other side of the core member (2) and composed of an Al—Si alloy. The sacrificial member (3) contains 0.03-0.30% by mass of Fe, 0.01-0.40% by mass of Mn, 0.4-1.4% by mass of Si, 2.0-5.5% by mass of Zn, not more than 0.05% by mass of Mg and the balance of Al and unavoidable impurities. In addition, the sacrificial member (3) has a crystal grain size of 100-400 & mgr;m after 5-minute heat treatment at 600 & ring;C during the brazing.
