PURPOSE:To manufacture the titled Al alloy excelling in strength and pitting resistance by incorporating specific percentage of Mn, Cu, Mg and Zn to Al. CONSTITUTION:The Al alloy consisting of, by weight, 0.6-1.5% Mn, 0.21-0.5% Cu, 0.1-1.0% Mg, 0.1-1.0% Zn and the balance Al and further containing, if necessary, >=1 kind among 0.05-0.25% Zr, 0.01-0.25% Ti, 0.05-0.25% Cr and 0.01-0.25% V is prepared. This Al alloy excels in strength and pitting resistance, so that it is useful as core material for laminate-type heat exchangers.
