    Abstract: Provided are a brazing furnace (1) and a brazing method in which brazing-joint quality can be easily stabilized in brazing with a reduced applied-amount of flux or in brazing without using flux. The brazing furnace (1) is configured to be used for brazing an object to be processed (100) composed of an aluminum material. The brazing furnace (1) includes a brazing chamber (2) equipped with heating apparatuses (21) that heat the object to be processed (100) to the brazing temperature, an inert gas supply apparatus (3) that supplies an inert gas in to the brazing chamber (2), and a dehumidifying apparatus (4) that is interposed between the inert gas supply apparatus (3) and the brazing chamber (2) and performs dehumidification of the inert gas.

    Abstract: An aluminum clad member is produced by: disposing a joining assistance member at a joint interface between an Al core member and an Al skin member, which joining assistance member being formed by crossing Al wires with each other in longitudinal and lateral directions to form a grid, and having a structure in which spot-like thick portions having a thickness of 0.2-3.2 mm are formed at intersections of the Al wires and arranged in the longitudinal and lateral directions so as to be spaced apart from each other by a distance of 0.2-13 mm; and performing a hot rolling operation with respect to the thus obtained stack of the Al core member, the Al skin member and the joining assistance member, by partially fixing together those members at their peripheral portions or without fixing together those members, such that the joint interfaces is communicated with an ambient air.

    Abstract: A brazing sheet brazing suitable for brazing performed in an inert gas atmosphere or in a vacuum without using a flux has a three-layer composition. An aluminum alloy core material contains Mg: 1.3 mass % or less. An aluminum alloy intermediate material is layered on the core material and contains Mg: 0.40-6.0 mass %. An aluminum alloy filler material is layered on the intermediate material and contains Si: 6.0-13.0 mass %, Bi: 0.0040-0.070 mass %, and Mg: 0.050-0.10 mass %.

    Abstract: A brazing sheet is provided for use in brazing performed in an inert gas atmosphere both using flux and without using flux. The brazing sheet includes an aluminum-based core, an intermediate material layered on the core and being composed of an aluminum alloy that contains Mg: 0.40-3.0 mass %, and a filler metal layered on the intermediate material and being composed of an aluminum alloy that contains Si: 6.0-13.0 mass % and Mg: less than 0.050 mass %. The brazing sheet satisfies the formula below where M [mass %] is the Mg content in the intermediate material, ti [μm] is the thickness of the intermediate material, and tf [μm] is the thickness of the filler metal: tf≥10.15×ln(M×ti)+3.7.
