PHOSBRAZ M73 Alloy with a higher fluidity, specially made for strong brazing of fitting, pipes and Fit up, with average joint gaps. It’s Phosphorus alloy with self-fluxing properties. The corrosion resistance this alloy is comparable to that of copper excepts when the joint is exposed to sulphur containing gas or at elevated temperatures as in a cooking range. Under these conditions, it is
expected that, this alloy will undergo progressive deterioration as other copper phosphorus alloy with Silver or without silver.
PHOSBRAZ M73 joining copper to copper it is act as self-fluxing alloy and does not required additional flux. It can be used on cuprous alloys (bronze, brass) with Phosbraz flux, electrical industry and Plumbing trade. 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. In Air conditioning and refrigeration application, PHOSBRAZ M73 can be used for the service temperature between +150˚C (without loss in strength) upto -20˚C. This alloy can be used for flam Maximum short service joint operating temperature 200˚C.
