Abstract:
Disclosed is an aluminum alloy clad material which includes a core material; a sacrificial anode material on one surface of the core material; and a filler material on the other surface of the core material and composed of an Al—Si alloy, in which the core material contains 0.3 to 2.0 percent by mass of Mn, 0.15 to 1.6 percent by mass of Si, 0.1 to 1.0 percent by mass of Cu, and 0.1 to 1.0 percent by mass of Mg, with the remainder including Al and inevitable impurities, the sacrificial anode material contains 7.0 to 12.0 percent by mass of Zn, 0.3 to 1.8 percent by mass of Mn, and 0.3 to 1.2 percent by mass of Si, with the remainder including Al and inevitable impurities, and has a thickness of 10 to 30 μm. The sacrificial anode material shows resistance to both local corrosion and general corrosion.
