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 that this company produce wire of 50 Cm in to Circular (2mm) cross section and Square (2*2 mm) cross section.Chemical and physical characteristics of these alloys are shown in table.
