Abstract

A method for producing an aluminum alloy clad material having a core material and a sacrificial anode material clad on at least one surface of the core material, wherein the core material comprises an aluminum alloy comprising 0.050 to 1.5 mass % (referred to as '%' below) Si, 0.050 to 2.0% Fe and 0.50 to 2.00% Mn; the sacrificial anode material includes an aluminum alloy containing 0.50 to 8.00% Zn, 0.05 to 1.50% Si and 0.050 to 2.00% Fe; the grain size of the sacrificial anode material is 60 μm or more; and a ratio R/Ris 0.30 or less, wherein R(μm) is a grain size in a thickness direction and R(μm) is a grain size in a rolling direction in a cross section of the core material along the rolling direction; a production method thereof; and a heat exchanger using the clad.
