Embodiment

[0116] Next, the present invention will be described in more detail based on examples of the present invention and comparative examples, but the present invention is not limited to these.

no. 1 Embodiment

[0117] First Example (Invention Examples 1-1 to 1-9, 1-19 to 1-28, Comparative Examples 1-10 to 1-18, 1-29 to 1-34)

[0118] First, the aluminum alloy fin material manufactured by the manufacturing method of 1st Embodiment is demonstrated.

[0119] Aluminum alloys having the alloy compositions shown in Table 1 were cast by DC casting, respectively, and both surfaces were surface cut for finishing. The thickness of the ingots after surface cutting was all set to 400 mm. The ingots of these aluminum alloys were subjected to the homogenization treatment step, the hot rolling step, the cold rolling step, and the annealing step under the conditions shown in Table 2. The plate thicknesses after hot rolling were all 3 mm. Then, in any order of (1) cold rolling → intermediate annealing → final cold rolling, (2) cold rolling → intermediate annealing → final cold rolling → final annealing, (3) cold rolling → final annealing , to make a finned material sample with a final plate thickn...

[0163] Second Example (Invention Examples 2-1 to 2-9, 2-19 to 2-26, Comparative Examples 2-10 to 2-18, 2-27 to 2-32)

[0164] Next, the aluminum alloy fin material manufactured by the manufacturing method of 2nd Embodiment is demonstrated.

[0165] Aluminum alloys having the alloy compositions shown in Table 1 were cast by DC casting, respectively, and both surfaces were surface cut for finishing. The thickness of the ingots after surface cutting was all set to 400 mm. The ingots of these aluminum alloys were subjected to the homogenization treatment step, hot rolling step, cold rolling step, and annealing step under the conditions shown in Table 5. The homogenized ingot was heated at 480° C. for 3 hours in the heating stage of the hot rolling process, and then passed to the hot rolling stage to obtain a hot-rolled sheet having a thickness of 3 mm. Then, in any order of (1) cold rolling → intermediate annealing → final cold rolling, (2) cold rolling → intermediate annealing ...
