Zusammenfassung:	PURPOSE:To form an oxide film on the surface of a Cu layer by coating the surface of aluminum alloy brazing filler metal with a Cu layer. CONSTITUTION:The surface of aluminum alloy brazing filler metal 1 is coated with a Cu layer 2. The composition of the aluminum alloy brazing filler metal is given by Al-8-15wt.%, Si-20-50wt.% of Zn. This brazing filler metal is used for the preplaced brazing of aluminum or its alloy material. In this way, a strong oxide film can be prevented from being formed on the surface of aluminum alloy brazing filler metal.
