Abstract
An aluminum alloy brazing sheet having a four-layered structure, of sheet thickness 0.2 mm or less, and having a core alloy, a filler alloy of an Al—Si alloy on one surface of the core alloy, a sacrificial anode material of an Al—Zn alloy on the other surface of the core alloy, and an intermediate layer between the core alloy and sacrificial anode material, wherein the core alloy is composed of an Al alloy containing given amounts of Si, Fe, Mn, and Cu, with the balance being made of Al and unavoidable impurities, and wherein the intermediate layer is composed of an Al alloy containing given amounts of Si, Fe, Mn, and Cu, with the balance being made of Al and unavoidable impurities.
