Zusammenfassung:	PURPOSE:To arbitrarily make composite brazing material contain a large quantity of Zn material by composing Al-Si alloy brazing material and Zn material or Zn-Al alloy material with the latter as a core. CONSTITUTION:Al-Si alloy brazing filler metal 1 and Zn material or Zn-Al alloy material 2 are composed with Zn material or Zn-Al alloy material 2 as the core to constitute composite brazing filler metal. The content occupied in all the composite brazing filler metal is given by Si; 8-15wt.%, Zn; 20-50wt.%. This composite brazing filler metal is used for brazing joining members such as aluminum alloy castings, die castings, high strength alloys of Al-Cu-Mg and Al-Zn-Mg. In this way, castings such as AC4C, die castings such as ADC12, ternary high strength alloys, etc., can be brazed.
