Harris 0HP is a higher phosphorus content version of the Harris 0 composition. This provides a lower melting temperature and a narrower melting range. It is an economical alloy designed for brazing copper to copper connections. This alloy flows quickly at brazing temperature and requires a close joint tolerance, preferably less than 0.004". It is used for manual braze applications but is frequently used in ring form for automated
brazing copper return bends in HVACR evaporator and condenser coils.

Harris 0HP is also a suitable choice for brazing brass. In this application operators should take care to avoid over heating the brass and use Harris Stay Silv ® white brazing flux.

Harris 0HP is not recommended for brazing steel or other ferrous base metals. The phosphorus content will form a low ductility intermetallic with the base metal.

CORROSION RESISTANCE
Generally similar to the copper base metal, but phosphorus containing alloys, including Harris 0HP, should not be used if the braze is exposed to sulfur or sulfur compounds in service.

AVAILABLE FORMS

Standard wire diameters in coils, rod and preform rings.

RECOMMENDED FLUX:
No flux is required for copper brazing. For brazing brass or copper to brass, use Stay-Silv ® white flux.
