Copper Phosphorus Brazing Alloys

Flux copper phosphorous brazing alloys are suitable for the fluxless brazing of copper and the brazing of copper alloys with flux. We recommend to use flux for copper alloys like brass and bronze joint. Pastes are formulated from alloy powders and specialty grade organic binders. Binders are chosen to decompose cleanly, well below brazing / working temperatures, leaving no residue. Several different environmentally friendly binder formulations are available. The above list is a standard range of our regular production, for any special request please do not hesitate to contact us directly or through our consultants.

Heat sources: Inert-gas continuous furnace H2/N2, cracked ammonia, exogas, vacuum furnace, acetylene torch, induction and resistance heating

Braze family of alloys is available in: wire, powder, paste, preforms, strip, ring and rods bare and flux coated
