Brazing is defined as a process of joining generally applied to metals in which, during or after heating, molten filler metal is drawn into or retained in the space between closely adjacent surfaces of the parts. Silver brazing alloys comprise a wide range of silver bearing compositions normally containing copper, zinc, phosphorous and in many cases, cadmium. For certain applications, limited additions of other elements, e.g. nickel, tin, etc. may be introduced.
The brazeable materials include silver brazing alloys, copper brazing alloys, phosphorus silver brazing alloys and brazing fluxes
