Abstract: Aluminum alloy material containing Si: 1.0 to 5.0 mass % and Fe: 0.01 to 2.0 mass % with balance being Al and inevitable impurities, wherein 250 pcs/mm2 or more to 7×105 pcs/mm2 or less of Si-based intermetallic compound particles having equivalent circle diameters of 0.5 to 5 μm are present in a cross-section of the aluminum alloy material, while 100 pcs/mm2 or more to 7×105 pcs/mm2 or less of Al-based intermetallic compound particles having equivalent circle diameters of 0.5 to 5 μm are present in a cross-section of the aluminum alloy material. An aluminum alloy structure is manufactured by bonding two or more members in vacuum or a non-oxidizing atmosphere at temperature at which a ratio of a mass of a liquid phase generated in the aluminum alloy material to a total mass of the aluminum alloy material is 5% or more and 35% or less.

Abstract: An aluminum alloy brazing sheet having high corrosion resistance is provided, which develops the sacrificial anticorrosion effect in both surfaces of the sheet, which has the brazing function in one of both the surfaces, and which prevents the occurrence of preferential corrosion. A channel forming component for a vehicular heat exchanger is also provided by utilizing the aluminum alloy brazing sheet. An aluminum alloy brazing sheet having high corrosion resistance includes an aluminum alloy core, a filler material clad on one surface of the core, and a sacrificial anode material clad on the other surface of the core, wherein the filler material, the sacrificial anode material, and the core have respective predetermined alloy compositions. A channel forming component for a vehicular heat exchanger is manufactured using the aluminum alloy brazing sheet having high corrosion resistance.
