Abstract
Disclosed is an aluminum alloy brazing sheet () for heat exchangers, the brazing sheet provided with a core material () and a filler material () that comprises an Al—Si—Zn alloy and is formed on at least one side of the core material (). The core material () has a pitting potential of −650 mV or more (vs. Ag/AgCl). The filler material () 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<d≦30. The filler material has a product (X×d) of the liquid fraction X and the clad ratio d (%) satisfying the relation 6≦X×d)≦23.
