Brazing rods (P:7%, Cu:Bal.), Phos-Copper/Phos-Copper-Silver, Silver-Copper-Zinc, Silver-Copper-Zinc-Tin Silver-Copper-Zinc

       Brazing rods (P:7%, Cu:Bal.)

       Copper-Phosphorus alloys have outstanding brazing properties and wide capabilities. Phosphorus will alloy readily with copper. Phosphorus is a reducing agent for copper and also deoxidizes silver. These brazing alloys of copper-phosphorus and silver-copper-phosphorus are self-fluxing on pure copper.

     The reduction of phosphorus and additions of silver have a profound effect upon the fluidity of brazing alloys. The alloys of higher phosphorus content are extremely fluid, while the lower phosphorus, high silver alloy has a broad plastic range. Even small adjustments in alloy percentages have a marked effect on brazing alloy fluidity.

       These brazing alloys are primarily used for joining copper and copper alloys and copper-phosphorus can be used for all brazing processes.
