A brazing-sheet manufacturing method includes superposing a core-material slab on or adjacent to at least one surface of a filler-material slab to form a clad slab, the core-material slab being composed of an aluminum material and the filler-material slab being composed of an Al—Si—Mg series alloy. Then, the clad slab is hot rolled to form a clad sheet having a core material layer composed of the aluminum material of the core-material slab and a filler material layer composed of the Al—Si—Mg series alloy of the filler-material slab. Then, the clad sheet is subjected to one or more passes of cold rolling. Either between cold-rolling passes or after the completion of the cold rolling, a surface of the clad sheet is etched using a liquid etchant that includes one or more inorganic acids. The liquid etchant does not contain fluorine atoms.

Method of manufacturing a brazing sheet

An aluminum alloy fin material for a heat exchanger is made of an aluminum alloy including 0.05 mass % to 0.5 mass % of Si, 0.05 mass % to 0.7 mass % of Fe, 10 mass % to 2.0 mass % of Mn, 0.5 mass % to 1.5 mass % of Cu, and 3.0 mass % to 7.0 mass % of Zn, with the balance being Al and unavoidable impurities. In an L-ST plane thereof, second-phase grains having an equivalent circle diameter equal to or more than 0.030 &#x3bc;m and less than 0.50 &#x3bc;m have a perimeter density of 0.30 &#x3bc;m/&#x3bc;mor more, second-phase grains having an equivalent circle diameter equal to or more than 0.50 &#x3bc;m have a perimeter density of 0.030 &#x3bc;m/&#x3bc;mor more, and specific resistance thereof at 20&#xb0; C. is 0.030 &#x3bc;&#x3a9;m or more.

In a brazing sheet manufacturing method, a cladding slab is prepared by overlaying at least a core-material slab composed of an aluminum material and a filler-material slab composed of an Al&#x2014;Si series alloy, in which a metal element that oxidizes more readily than Al is included in at least one of the slabs. A clad sheet is prepared by hot rolling this cladding slab, which then has at least a core material layer composed of the core-material slab and a filler material layer composed of the filler-material slab and disposed on at least one side of the core material. Then, a surface of the clad sheet is etched using a liquid etchant that contains an acid. Subsequently, the clad sheet is cold rolled to a desired thickness. In flux-free brazing, such a brazing sheet is capable of curtailing degradation in brazeability caused by fluctuations in dew point and oxygen concentration.
