ChannelFlux Silver® A-38T

A general purpose brazing alloy providing good flow and ductility. Forms good fillets and is an economical alternative to other cadmium-free alloys. ChannelFlux® Silver A-38T is used for brazing ferrous metals, copper, copper alloys, nickel, nickel alloys and combinations of these metals. The tin content provides good wetting on many difficult to wet metals such as stainless steel and tungsten carbide. The greatest use of this alloy is during furnace brazing, although it is also suitable for other brazing procedures.
