ABSTRACT:
A brazing process for joining copper and copper alloy tubes to a fitting which includes first forming a layer of a high melting temperature noble metal on one end of a copper or copper alloy tube. The plated end is then brazed to a metal ferrule to form a copper alloy-ferrule assembly. The assembly is then furnace brazed to a metal fitting.
