#31- Roll-Bonded Clad Metal Foils as Ag-Cu-Ti Active Brazing Filler Metals
Abstract: Ag-based active brazing filler metals have been developed at Materion Technical Materials and are employed to join ceramic and metal/ceramic components by brazing. These active brazing alloys promote wetting of the ceramic surfaces during brazing, and obviate the costly, intermediate step of surface treatment (e.g. metallizing) of the ceramic components. Ag-Cu-Ti active brazing filler metals typically require powder metallurgy fabrication.
This paper describes an alternative manufacturing approach to make Ag-based active brazing alloys in foil form through roll-bond cladding. Clad brazing filler metals were produced at Materion Technical Materials by cold roll-bonding and further processed into thin multilayer clad foils. The differential thermal analysis and advantages of these brazing alloys are discussed.
