A method of producing an aluminum alloy fin material for brazing, which comprises: casting an aluminum alloy by continuous cast-rolling, wherein the alloy comprises above 0.1 wt% to 3 wt% of Ni, above 1.5 wt% to 2.2 wt% of Fe, and 1.2 wt% or less of Si, and at least one of Zn, In, and Sn in given amounts, the balance being unavoidable impurities and aluminum, and cold-rolling in which annealing at 250 to 500 DEG C is conducted plural times midway in the cold-rolling, thereby producing the fin material of a given thickness; wherein a cast coil with a given thickness is produced by continuous cast-rolling, and wherein the second last annealing is carried out with a given thickness, and wherein the final annealing is carried out under heating conditions that do not allow complete recrystallization. <IMAGE> |
