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.

Abstract: This cladded aluminum-alloy material is provided with: an aluminum alloy core material, a coating material used to clad both surfaces of the core material; and a brazing material used to clad both of the coating material surfaces, or one of the coating material surfaces which is not at the core material side. The core material, the coating material and brazing filler material have described alloy compositions. The crystal grain size of the coating material before brazing heating is at least 60 μm. In a cross section of the core material in the rolling direction before brazing heating, when R1 (μm) represents the crystal grain size in the plate thickness direction, and R2 (μm) represents the crystal grain size in the rolling direction, R1/R2 is not more than 0.50. As a result, the cladded aluminum-alloy material exhibits excellent mouldability, and the coating material after brazing heating exhibits excellent corrosion resistance.
