ABSTRACT:
The present invention relates to an aluminum alloy brazing sheet (1) for a heat exchanger improved in a life including a fatigue in a plastic area and an aluminum alloy heat exchanger tube (11) using the brazing sheet, which is composed of: a core material (2) of an Al—Mn series alloy; a skin material (3) of any one of an Al—Zn series alloy, an Al—Zn—Mg series alloy, an Al—Si—Mn—Zn series alloy, and an Al—Si—Mn—Mg—Zn series alloy clad on one side of the core material; and a brazing material (4) of an Al—Si series alloy clad on the other side of the core material, and is adapted so that an X-ray diffraction intensity ratio of the aluminum alloy brazing sheet satisfies a relational expression of I200/(I111+I200+I220+I311)≧0.4.
