Abstract

PURPOSE: The titled Al-alloy clad material excellent in pitting corrosion resistance, obtained by using an Al-alloy containing Cu and Mn in a specific amount as a core material and high purity Al obtained by a smelt casting method as a skin material.
CONSTITUTION: An Al-alloy containing, on a wt. basis, 0.2W0.8% Cu, 0.1W0.8% Mn and one or more of an element amount 0.1W0.6% Mg, 0.1W0.6% Si, 0.01W 0.3% Cr, 0.01W0.3% Zr and 0.01W0.3% Ti and comprising the remainder of Al and inevitable impurities is used as a core material while pure Al with purity of 99.5% or more obtained from a cast ingot by a smelt casting method is used as a skin material. The potential difference of the core material and the skin material is about 50mV or more in any case while the natural electrode potential of the skin material itself is about -750mV or less and a Al-alloy clad material for a heat exchanger excellent in pitting resistance is obtained by using said core material and said skin material.
