Session Description: This session will discuss the development and use of new brazing filler metal compositions. The focus of first half of the session will be on the brazing of stainless steels and super-alloys using newly developed low-cost brazing filler metals. The remainder of the session will address recent developments using precious-metal based brazing filler materials. Material properties and application information that will be beneficial for process engineers and brazing technicians will be presented.
