J.W. HARRIS brazing alloys are the cleanest and brightest alloys made. Free of oxide and surface impurities, the purity of Harris alloys runs all the way through the rod. Purity makes a huge difference in the integrity of a 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 than Harris.

J.W. Harris produces the highest quality phosphorus/copper brazing rod in the world. The proprietary production technology Harris developed to manufacture these alloys is still unique today. The alloy's phosphorous content is controlled to a tolerance five times tighter than industry requires. Such tight control means absolute consistency in application and performance with every rod, every batch.

FLASH™ has a substantially lower melting temperature than standard 0% silver alloys resulting in less annealing of and less damage to the base metal. Brazing time is faster. Cycle time is less. FLASH™ is an economical and fast-flowing phos/copper alloy ideally suited for all manufacturing applications - both manual and automatic - where fast, sound, cost-effective connections are essential. No one else has FLASH™ - only J.W. Harris.

Dynaflow® is an exceptionally pure, phos/copper/silver brazing alloy recommended for all copper-to-copper and copper-to-brass cooling applications. Harris invented Dynaflow® years ago as an economical alternative to 15% silver alloys, and through the years, the serviceability and economic benefits of Dynaflow® have made it a familiar and standard replacement for 15% in the HVAC/R industry. Dynaflow® is a premium, medium-range silver alloy, formulated to even tighter specifications than the Stay-Silv® alloys to mirror the performance characteristics of the 15% silver brazing filter metals. Excellent for brazing both tight and poorly-fitted connections, Dynaflow's proven reliability and acceptance by field service engineers have made it the leading choice of brazing operators.
