Patent ID: 8668993

Claim:
An aluminum alloy clad material comprising: a core material; a sacrificial anode material present on one surface of the core material; and a filler material present on the other surface of the core material and, which comprises an Al—Si alloy, the core material consisting of: 0.3 to 2.0 percent by mass of manganese (Mn), 0.15 to 1.6 percent by mass of silicon (Si), 0.1 to 1.0 percent by mass of copper (Cu), 0.1 to 1.0 percent by mass of magnesium (Mg), and optionally, 0.01 to 0.5 percent by mass of at least one selected from the group consisting of titanium (Ti), zirconium (Zr), and niobium (Nb), with the remainder including aluminum (Al) and inevitable impurities, the sacrificial anode material consisting of: 9.0 to 12.0 percent by mass of zinc (Zn), 0.3 to 1.8 percent by mass of manganese (Mn), 0.3 to 1.2 percent by mass of silicon (Si), and optionally, 0.01 to 0.5 percent by mass of at least one selected from the group consisting of titanium (Ti), zirconium (Zr), and niobium (Nb), with the remainder including aluminum (Al) and inevitable impurities, and the sacrificial anode material having a thickness of from 10 to 30 μm.
