Abstract:
A fin material made of an aluminum alloy for heat exchangers contains 1.0 to 2.0 mass % of Mn, 0.7 to 1.4 mass % of Si, and 0.05 to 0.3 mass % of Fe, and one or more kinds of 0.05 to 0.3 mass % of Zr, 0.05 to 0.3 mass % of Cr, and 0.05 to 0.3 mass % of V, with the balance being Al and unavoidable impurities, in which a number density of intermetallic compounds having a circle-equivalent diameter of 0.025 to 0.4 μm before braze-heating is 3.0×10 6  particles/mm 2  or more, an amount of solid solution of Mn is 0.3 mass % or less and a respective amount of solid solution of Zr, Cr, and V is 0.1 mass % or less, and a recrystallization completion temperature during a temperature rise at the time of braze-heating is 450° C. or less.

Claim (Index 2):
