Copper / phosphorus alloys
Copper/phosphorus alloys are exclusively intended for the brazing of copper and its alloys.
They are self-fluxing on copper. For brass, we recommend you use SOPHOS-FLUX.

Copper / phosphorus silver alloys
The silver content of these alloys increases significantly the mechanical characteristics of brazed joints. These alloys are used for the brazing of copper connector fittings in electrical and refrigeration industries, etc.
