An aluminum alloy fin material for brazing which is composed of an aluminum
alloy comprising 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 selected from the
group consisting of 4 wt % or less of Zn, 0.3 wt % or less of In, and 0.3
wt % or less of Sn, and further comprising, optionally, at least one
selected from the group consisting of co, Cr, Zr, Ti, Cu, Mn, and Mg in
given amounts, the balance being unavoidable impurities and aluminum,
wherein a ratio of the grain length in the right angle direction/the grain
length in the parallel direction is 1/30 or less, an electric conductivity
is 50 to 55 %IACS, and a tensile strength is 170 to 280 MPa.
