Abstract
An aluminum-alloy, fin material is composed of a brazing sheet containing a core material and filler material(s) disposed on both sides of the core material. The core material is an aluminum alloy containing 0.02-0.80 mass % Si, 0.02-0.80 mass % Fe, and 0.8-2.0 mass % Mn. The core material has a crystalline-aggregate structure in which: the orientation density of one or more of brass orientation, copper orientation, and S orientation is 20 times or more that or those of a randomly oriented sample; and the orientation densities of cube orientation, CR orientation, and P orientation are each 10 times or less than those of the randomly oriented sample. The filler material(s) is (are) composed of an Al—Si series alloy that contains 6.0-13.0 mass % Si and 0.02-0.80 mass % Fe. The clad percentage of filler material(s) is 6-16% of the total thickness of the brazing sheet.
