摘要：
Disclosed is an aluminum alloy brazing sheet (1) for heat exchangers, the brazing sheet provided with a core material (2) and a filler material (3) that comprises an Al—Si—Zn alloy and is formed on at least one side of the core material (2). The core material (2) has a pitting potential of −650 mV or more (vs. Ag/AgCl). The filler material (3) has a zinc concentration of from 1 to 10 percent by mass; a liquid fraction X, at the brazing temperature, satisfying the relation 0.3≦X≦0.88; and a clad ratio d (%) satisfying the relation 15
