The Copper Phosphorus Brazing Alloys are suitable to join copper with copper alloy base materials such as brass and bronzes. The compound with high proportion of phosphorus will result in a more active and fluid alloy which can flow over a larger area. The alloys have self-fluxing properties when used on copper. The phosphorous content determines the precise melting temperature and performance.

Higher proportion of silver alloy will result in a fluid which is easier to be controlled by operators. The silver alloy with less phosphorus may have a melting range which suitable for filling gaps. Generally, higher silver content alloy can bear hotter or longer heating cycle. Moreover, the resulted joints have better ductility.
