Abstract:
The purpose of the invention of the present application is to provide an aluminum alloy brazing sheet able to achieve excellent brazing properties by effectively weakening an oxide film on a brazing surface. This aluminum alloy brazing sheet is obtained by cladding a brazing material, which contains 6-13% of Si, with the remainder consisting of Al and unavoidable impurities, on one or both surfaces of an aluminum alloy core material and is used to braze aluminum in an inert gas atmosphere or in a vacuum, wherein the aluminum alloy brazing sheet is characterized in that cladding is effected by interposing a plate-like material between the core material and the brazing material, the plate-like material containing one or more elements selected from among 0.05% or more of Li, 0.05% or more of Be, 0.05% or more of Ba, 0.05% or more of Ca and 0.4% or more of Mg, with the remainder consisting of Al and unavoidable impurities.
