Abstract
A clad aluminum alloy material exhibiting favorable corrosion resistance and brazeability in an alkaline environment is shown by a clad aluminum alloy material with excellent brazeability and corrosion resistance in which one surface of an aluminum alloy core material is clad with a sacrificial anode material and the other surface is clad with brazing filler material. The core material includes an aluminum alloy of Si: 0.3-1.5%, Fe: 0.1-1.5%, Cu: 0.2-1.0%, Mn: 1.0-2.0%, and Si content+Fe content ≥0.8%, wherein the 1-20 μm equivalent circle diameter Al—Mn—Si—Fe-based intermetallic compound density is 3.0×10to 1.0×10pieces/cm, and the 0.1 μm to less than 1 μm equivalent circle diameter Al—Mn—Si—Fe-based intermetallic compound density is at least 1.0×10pieces/cm. The sacrificial anode material includes an aluminum alloy containing Si: 0.1-0.6%, Zn: 1.0-5.0%, and Ni: 0.1-2.0%.
