Abstract
An aluminum alloy fin material for brazing, characterized by comprising an aluminum alloy comprising more than 1.4% by mass but not more than 1.8%
by mass of Fe, 0.8% by mass or more but 1.0% by mass or less of Si, and more than 0.6% by mass but not more than 0.9% by mass of Mn, with the balance being Al and inevitable impurities, wherein 80% or more of the surface area, as viewed from the surface layer of the fin plane, is occupied by recrystallized grains with a length of 10 mm or more, in a direction rolled.
by mass of Fe, 0.8% by mass or more but 1.0% by mass or less of Si, and more than 0.6% by mass but not more than 0.9% by mass of Mn, with the balance being Al and inevitable impurities, wherein 80% or more of the surface area, as viewed from the surface layer of the fin plane, is occupied by recrystallized grains with a length of 10 mm or more, in a direction rolled.
