CuP-AG 5% Manual Brazing


PHOSBRAZ AG50 is CuP alloy with Silver and lowers the liquids point, the greater the ductility of the brazed joint. This addition also refines the alloy, increasing the brazed joints mechanical characteristics and improving electrical conductivity. This is special alloy for high strength capillary brazing. This brazing alloy is not recommended to be used for the media having sulphur. Also it is not allowed to use for joining steels (Fe) or materials containing Iron (Fe), Nickel (Ni), Cobalt (Co) as it will form brittle phase in the joint. The corrosion resistance of this alloy is comparable to that of copper excepts, when the joint is exposed to sulphur containing gas or at elevated temperatures. Under these conditions, it is expected that, this alloy will undergo progressive deterioration as other copper phosphorus alloy with Silver or without Silver.

PHOSBRAZ AG50 is recommended for hard brazing of copper and optionally copper brass pipes of
combustible installations. As well as all low temperature applications. In Air conditioning and refrigeration application, PHOSBRAZ AG50 can be used for the service temperature between +150˚C (without loss in strength) to -50˚C. This alloy can be used with flame.
