PURPOSE:To obtain a Cu-Ag type alloy brazing filler metal of a low content of Ag having good brazing property, and low vapor pressure by forming said material of the composition consisting of specific amts. of Ag, Si, and Cu. CONSTITUTION:The alloy brazing filler metal is constituted of the composition consisting of 5-35 Ag, 2.5-13 Si by wt% and the balance Cu and unavoidable impurities or the composition consisting of adding 1-10 of one or >=2 kinds Sn, In to this and the balance Cu and unavoidable impurities. Such Cu-Ag type alloy brazing filler metal of a low content of Ag has good brazing stickability and low vapor pressure despite the extremely low content of Ag as compared to conventional Cu- Ag type and Ag-Cu-Sn alloy brazing filler metals. |
