摘要： An aqueous aluminum brazing composition containing an organic binder and zinc-based flux which prevents precipitation of the zinc-based flux having a large specific gravity while securing excellent brazeability. The thixotropic index of the brazing composition is adjusted to 1.01-1.20 by adding (meth)acrylic acid/(meth)acrylate copolymer emulsion to the brazing composition as a precipitation inhibitor in an amount of 0.03-1.50 wt % of 100 wt % of the brazing composition. Since the (meth)acrylic acid/(meth)acrylate copolymer emulsion is used as the precipitation inhibitor in a specific amount instead of other types of compounds used for powder-containing paint such as ultrafine particle silica, poly(meth)acrylate, or polyvinyl alcohol, precipitation of the zinc-based flux can be prevented without impairing brazeability.

摘要： A sheet material for the tube 10 includes: a core material 10b; and a sacrifical corrosion material 10c clad on one face of the core material 10b which becomes an outside of the tube 10. A sheet material for the fin is a bare aluminum material on which a brazing filler metal is not clad. A mixture composition 10e, in which powder of a brazing filler metal and flux are mixed with each other, is coated on the outside of the tube 10. The tube 10 and the fin are brazed to each other with this mixture composition 10e. Even after the completion of brazing, the sacrifical corrosion material 10c remains on the outside of the tube 10.
