PURPOSE:To obtain the titled Al alloy which shows high strength, excellent brazability and corrosion resistance by incorporating Mg, Si, Fe and Ni to the alloy and furthermore incorporating one or two kinds from either or both groups between the one of Mn, Cr, Zr, etc., and the other of Zn, In and Sn thereto. CONSTITUTION:The Al alloy for an exchanger member contg., by weight, 0.01-1% Mg, 0.01-1.5% Si, 0.01-1% Fe and 0.05-5% Ni and furthermore contg. 1 or >=2 kinds from either or both groups between the one of 0.01-2% Mn, 0.001-0.5% Cr, 0.001-0.5% Zr, 0.001-1.5% Hf, 0.001-0.5% Ti and 0.0001-0.1% B and the other of 0.5-5% Zn, 0.005-0.5% In and 0.005-0.5% Sn is provided. The Al alloy clad material for a heat exchanger member in which said Al alloy is formed to the core and in which the Al alloy wax material contg. >=5wt.% Si is clad on either face or both faces thereof has the excellent characteristics as well equal to said Al alloy.
