The Harris Stay-Silv 15 PhosCopper Brazing Alloy is the industry standard for air conditioning and refrigeration applications. Still widely used, but now often replaced by Dynaflow® in many HVAC/R applications. For many years the standard of the industry, the 15% silver alloy has proven its value. This filler metal is excellent for situations in which close fit-up does not exist, and where thermal expansion and service vibration are involved.

The Harris Blockage Phosphorus Tin Silicon Brazing Alloy is a proprietary phosphorus-tin-silicon alloy engineered as an inexpensive alternative to copper-copper and copper-brass alloys. It is self-fluxing on copper and its lower melting temperature makes it an excellent choice for brass connections. BLOCKADE flows rapidly but can be used to “cap” brazed joints.
Blockade’s® unique silicon addition offers significant advantages over phos/copper and silver/phos/copper, (BCuP), brazing alloys. Among the benefits are: bright alloy color during cooling that allows visual verification of a good braze joint, improved ductility over BCuP-2 alloy, reduced brazing temperature, and reduced material costs. It is often used with Stay-Silv® white brazing flux as a replacement for high silver alloys when brazing brass.

The important advantage of Stay-Brite® solders is the greater strength of the overall component. After joining, its lower working temperature eliminates the weakening of the base metals caused by annealment from high brazing heat. The result is a stronger, more economical joint.
Stay-Brite® silver bearing solders have the same excellent affinity as SafetySilv® alloys for bonding with most of the ferrous and nonferrous alloys (including stainless steel, nickel, copper, brass, etc.) It provides a considerably higher than necessary elongation for sound dissimilar metal joints and vibration applications.
Stay-Brite® alloys range in temperature from 430°F to 535°F. Stay-Brite® solder eliminates oxide scale formed from brazing heat. No nitrogen purge is required for HVAC/R tubes. They are cadmium free and nontoxic. Stay-Brite® is a eutectic alloy with a single melting point of 430°F (221°C).

The Harris Stay-Silv 5 medium-silver PhosCopper brazing alloy is designed for copper to copper applications. It can also be used on copper to low zinc brass but this application requires use of Stay Silv white brazing flux.
Like many phosphorus/copper brazing filler metals Stay Silv 5 will flow rapidly when heated quickly to its liquidus. This allows penetration into tight clearance connections. With slower heating, the alloy melting range provides the ability to filler wider gaps.
Stay Silv 5 is often chosen as an economical alternative to higher silver content alloys for copper and brass applications.
Stay Silv 5 is not recommended for brazing steel or other ferrous base metals. In these applications the phosphorus content promote
