J.W. Harris brazing alloys are the cleanest and brightest, free of oxide and surface impurities. Other brazing alloys just don't meet Harris standards. Compare our alloys with others -- you can see the difference. Harris alloys are pure and shiny, and the purity runs all the way through the rod. What a huge difference purity makes in the integrity of your brazed joint.
Leaks are caused by oxide and impurities -- CONTAMINATION -- that enter the joint in the molten metal of an impure brazing alloy and impede the brazing alloy flow. Wherever there is contamination, the alloy flows around it, leaving pinholes in the joint. These pinholes are tiny doors which allow refrigerant gas to leak out. Leaks are expensive -- the serviceman has to return to the job to rebraze the joint and must refill the expensive refrigerant that was lost from the leaks. When properly brazed, the biggest difference between a Harris joint and a joint brazed with another brand is reliability. You won't find a more dependable brazing alloy, because you won't find a cleaner one.
J.W. Harris produces the highest quality phosphorus/copper brazing rod in the world. The alloys' phosphorus content is controlled to ±1/10 of one percent, a tolerance five times tighter than industry requires. This results in a guaranteed liquidus temperature of ±6°F/±3.3°C.
Stay-Silv 5 and Stay-Silv 6: Medium-range alloys; Stay-Silv 5 is useful primarily where fit-up can not be tightly controlled.
Dynaflow: Premium, medium-range silver alloy, formulated to even tighter specifications than the StaySilv alloys to mirror the performance characteristics of the 15% silver brazing filler metals. Excellent for brazing both tight and poorly-fitted connections, Dynaflow's proven reliability and acceptance by field service engineers has made it the leading choice of brazing operators.
Stay-Silv 15: For many years, the industry standard for air conditioning / refrigeration applications.
