These alloys do not need the use of fluxes when employed to braze copper-to-copper; however, a flux is required when joining copper to copper alloys (e.g. brass).
Phosphorus-containing alloys are not suitable for joining ferrous or nickel-containing metals.
In order to avoid corrosion, the exposure of the joint to sulphurus-containing atmospheres is not recommended.
