Recently, new and improved brazing filler metals with selffluxing has been produced by rapid solidification in Cu-P based alloys. As the industrization goes on, it is required to decrease properly the brazing temperature of filler metals with good brazed joint characteristics such as mechanical strength, electrical properties etc. The brazed joint characteristics and the formation of amorphous were compared Zr-containing Cu-P based filler metal with Zr-free Cu-P based filler metal. As a result, it has been concluded that the brazed joint characteristics were simillar each other between the above two filler metals, and grass forming ability was accelerated by Zr addition. |
