Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a brazing filler metal composed of copper phosphorus brazing metal alloy that can be easily cold-worked into a thin sheet, and also to provide a brazing sheet that has a brazing filler metal layer of this alloy. SOLUTION: The copper phosphorus brazing filler metal contains 2.0-3.2%, desirably 2.2-2.9% P in mass %, with the balance formed with copper phosphorus brazing metal alloy consisting substantially of Cu. The brazing sheet 1 is composed of a metallic sheet 2 and a brazing filler metal layer 3 integrally pressure-welded to at least one surface of the sheet, with the brazing filler metal layer 3 formed with the copper phosphorus brazing metal alloy. The metallic sheet 2 can be formed with Cu or a Cu alloy having Cu as the main component. COPYRIGHT: (C)2004,JPO
