The Si brazing material is used to join the tube material and the fin material and the tube material to the header plate during brazing, and the sacrificial anode skin material mainly corrodes the skin material due to differences in the core material and electrochemical properties. And it has the function of suppressing pitting corrosion of the core material. When these aluminum alloy clad materials are used in a heat exchanger as a tube material for a radiator or a heater core, the refrigerant exhibits an excellent sacrificial anode effect in a weakly acidic to neutral region. However, the cooling water actually used shows alkalinity mixed with LLC (Long Life Coolant) composed of antifreeze and rust preventive. When the refrigerant is an alkaline solution having a pH of 9 or more, corrosion resistance is still insufficient. Pitting corrosion may occur early or the anticorrosion effect may not be sufficiently exhibited.
