Copper-Phosphorus alloys have outstanding brazing properties and wide capabilities. 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 addition 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 has a broad plastic range. These alloys are available in forms of wire, rod, strip, ring and etc. Chemical and physical characteristics of these alloys are shown in table.
