Highly corrosion-resistant aluminum alloy brazing sheet, and the flow path forming part of the heat exchanger for an automobile using the same

摘要

PROBLEM TO BE SOLVED: To provide a high corrosion resistance aluminum alloy brazing sheet which has brazing capability on one surface thereof, in addition to sacrificial anti-corrosion effect on both surfaces thereof, and prevents the occurrence of preferential corrosion, and a flow path forming component for automotive heat exchanger which uses the same.SOLUTION: The high corrosion resistant aluminum alloy brazing sheet is provided with an aluminum alloy core material, a brazing material cladded on one surface thereof, and a sacrificial anode material cladded on the other surface thereof. The brazing material, the sacrificial anode material and the core material have predetermined alloy compositions, respectively. The flow path forming component for automotive heat exchanger uses the brazing sheet.
