Abstract:
An aluminum alloy clad sheet for heat exchangers includes a core layer, a sacrificial layer disposed on one side of the core layer, and a brazing layer of an Al—Si alloy disposed on the other side of the core layer, wherein the core layer contains Si: 0.15% to 1.6% by mass, Mn: 0.3% to 2.0% by mass, Cu: 0.1% to 1.0% by mass, Ti: 0.02% to 0.30% by mass, and the remainder of Al and incidental impurities, and the sacrificial layer contains Zn: 4.0% to 10.0% by mass, Cr: 0.01% to 0.5% by mass, and the remainder of Al and incidental impurities.
