According to Ambrell Group Application Labs talking about filler metals: Silver is frequently used for induction brazing because of its low melting point.
The life of the fixturing is substantially increased because problems due to repeated exposure to heat (such as distortion and metal fatigue) are eliminated.
This ability to create clean and controllable joints is one of the reasons that induction brazing is being used extensively for high-precision, high-reliability applications.
Batch vacuum furnaces solve these problems, but have significant limitations of their own because of their large size, poor efficiency and lack of quality control.
“An induction brazing system quickly delivers highly localized heat to minimize part warpage and distortion.
Induction brazing is a very repeatable process because variables such as time, temperature, alloy, fixturing, and part positioning are very controllable.
