An aluminum alloy clad material for heat exchangers exhibiting excellent erosion-corrosion resistance, corrosion resistance, pitting resistance, and brazability, which is suitably used as an aluminum alloy clad sheet for forming a constituent member, in particular, a tube for an aluminum heat exchanger such as a radiator and heater, and as a pipe for circulating a working fluid in the aluminum heat exchanger or a pipe connected to the heat exchangers. The aluminum alloy clad sheet comprises a sacrificial anode material clad on one side of a core material, wherein the core material comprises an Al--Mn alloy and the sacrificial anode material comprises an aluminum alloy, for example, an aluminum alloy comprising 3.0-12.0% of Si with the remaining portion consisting of Al and impurities, or an aluminum alloy comprising 3.0-12.0% of Si, 1-10% of Zn, and 0.15-1.2% of Fe with the remaining portion consisting of Al and impurities. The sacrificial anode material may comprise trace amounts of one or more of In, Sn, and Mg. The clad sheet may have a three-layered clad material in which an Al--Si-type brazing material is clad on the side of the core material.
