Silver-phos-copper
HZ-BCuP is a copper phosphorus brazing filler metal containing a nominal **9%
phosphorus. It is primarily used for the
brazing
of copper, although it can also be used for brazing copper alloys. When brazing copper the
phosphorus within the
alloy imparts a metallurgical based self-fluxing capability. HZ-BCuP does not contain a flux core or flux coating.
If used to
join copper alloys (such as brass, bronze or gun metal) a separate flux will be required because the self-fluxing action only
occurs on copper (see below for details).
This filler metal should not be used to braze iron containing materials like carbon or stainless steels or nickel containing
materials as the phosphorus within the filler metal will form brittle, intermetallic, phosphide compounds at the joint
interface. HZ-BCuP is not suitable for use in sulphurous atmospheres at elevated service temperatures.
When selecting a copper-phosphorus brazing filler metal it is necessary to understand about their flow
properties and ductility.
The level of phosphorus within the filler metal controls these two characteristics - the higher this is the
more free
flowing the filler metal and the lower its ductility.
HZ-BCuP is the most free flowing copper-phosphorus filler metal. However, due to its high phosphorus
content it is one of
the least ductile. The low ductility of the alloy imparts it with glass like properties, making it both notch
sensitive and
sensitive to impact type loadings. This filler metal should therefore not be used in applications involving exposure to
strong
vibration, impact loads or where some deformation of the joint might be expected in service. In such
circumstances
the use of the more ductile HZ-Ag*5P Ag-Cu-P brazing alloy or HZ-Ag5P Ag-Cu-P filler metals should be
considered. HZ-BCuP is best suited for making copper joints that are of the true capillary type and
where tight joint clearances of
0.****0.**5 mm are used. The use of bell mouthed type joints should be avoided. HZ-BCuP can be
used to
braze copper alloys, but its lack of ductility can be exposed in such applications.

Product uses: It is widely used in the refrigeration, heating and ventilating and air conditioning industries for the brazing of copper pipe-work systems.
Conditions for use: Flame heating methods are most often used for brazing with it. When used as a ring, rapid heating to
the brazing temperature is required to avoid liquation (separation of low and high melting phases in the alloy).
For brazing copper to copper no flux is needed, as HZ-BCuP is self-fluxing in this case.
For use on copper alloys a separate flux is required and HZ-QJ**1 and HZ-QJ**2 Flux Powder is recommended.
