摘要： A brazing sheet for flux-free brazing, comprising a core material, a brazing material disposed on at least one surface of the core material, and a thin skin material disposed on the brazing material, wherein the core material is made of an aluminum alloy having a higher melting point than that of the brazing material; the brazing material is made of an Al—Si—Mg based alloy and has a thickness of 25 to 250 μm; the thin skin material is made of an aluminum alloy having a higher melting initiation temperature than the brazing material and containing substantially no Mg, and has a thickness of 5 to 30 μm; and a content of an oxide existing at an interface between the brazing material and the thin skin material is 0.1 ppm or less in weight ratio with respect to the entire clad material. The present invention provides a brazing sheet for flux-free brazing, which has a thin skin material, with uniform brazing characteristics, and enables stable joining.
