Abstract

An aluminum alloy brazing sheet having 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 which has a superior corrosion resistance to an exhaust gas condensate water after the brazing process is disclosed. A method of manufacturing of the aluminum alloy brazing sheet also is disclosed. A high corrosion-resistant heat exchanger that employs the aluminum alloy brazing sheet also is disclosed.
