Brazing Alloys for Copper
Join copper and copper alloys in general purpose applications. These alloys don’t contain any cadmium, so they’re safer to use than brazing alloys with cadmium and help meet industry regulations.
BCuP-4 alloys have higher silver content than BCuP-6 alloys, so they flow more easily.
