Abstract: |
Silver based brazing filler metals have been used in a wide range of fields as the easiest brazing material. Therefore, the type of silver brazing filler metals is the largest among brazing filler metal. In recent years, ISO Ag156 has been the most widely used silver based brazing filler metal with low melting point and easy to use since the use of Cd was prohibited from environmental problems. However, silver based brazing filler metals have become expensive brazing filler metal due to price increase of silver compared to before, so that low price brazing filler metal containing less silver becomes market demand. In this study, brazing filler metal with 40wt% of silver content and below 700 degrees C of melting point was developed.
