摘要
A brazing sheet (5) comprises a thin covering material (2) and a core material (3) as well as an Al-Si alloy brazing material (1) interposed between the thin covering material and the core material. The brazing material further contains Mg, Bi and/or Zn, Sn, In. When the above brazing material is molten in an inert gas atmosphere, this molten brazing material seeps onto the surface of the above thin covering material, whereby the brazing sheet is fluxlessly brazed to joint materials.
