摘要：Problem;To provide an aluminum alloy brazing sheet, featuring a good brazing property that prevents diffusion of molten filler material in a core material of the aluminum alloy brazing sheet during a brazing process and exhibiting a superior corrosion resistance to an exhaust gas condensate water after the brazing process, a method of manufacturing the aluminum alloy brazing sheet, and a high corrosion-resistant heat exchanger using the aluminum alloy brazing sheet.;Resolving Means;A high corrosion-resistant aluminum alloy brazing sheet comprises a core material composed of an aluminum alloy, a sacrificial anode material cladded on one surface of the core material, and a filler material composed of an Al/Si-based alloy and cladded on another surface of said core material, and is characterized in that the sacrificial anode material is composed of an aluminum alloy which contains Si falling within a range of 2.5-7.0 mass %, Zn falling a range of 1.0-5.5 mass %, Fe falling within a range of 0.05-1.0 mass %, and which is composed of the balance Al and the inevitable impurities, and that a clad thickness of the sacrificial anode material falling within a range of 25-80 μm. Also, there is provided a method of manufacturing the aluminum alloy brazing sheet, and a high corrosion-resistant heat exchanger using the aluminum alloy brazing sheet.
