Harris Handy-Flo-6 6% Silver Brazing Alloy Stick

Product Description

The HARRIS Handy-Flo-6 is a copper-phosphorus-silver brazing alloy rod used to join copper and brass components in refrigeration, HVAC, and plumbing systems. The alloy composition is 6 percent silver, 6 percent phosphorus, and 88 percent copper. When joining copper to copper, the phosphorus content acts as a self-fluxing agent, eliminating the need for a separate flux. For copper-to-brass joints, a flux is recommended. Among the Sil-Fos family of alloys, this rod delivers the highest joint ductility, making it well suited for applications where vibration or thermal cycling is a concern. Licensed HVAC technicians and plumbers are the primary installers of this product.

The Handy-Flo-6 is designed for use in residential and light commercial HVAC and refrigeration systems, as well as plumbing applications involving copper tubing and fittings. Its slow-flow characteristic gives technicians more control during the brazing process, particularly on vertical joints or when working with larger-diameter tubing. The self-fluxing property on copper-to-copper joints reduces prep time and material cost on common service calls. It is manufactured in the USA.

Key Features

• Self-fluxing on copper-to-copper joints due to phosphorus content — no separate flux required
• Flux recommended when joining copper to brass
• Highest joint ductility in the Sil-Fos alloy family — resists vibration and thermal stress
• Slow-flow formulation provides increased control during brazing
• 6 percent silver content improves wetting and joint strength over non-silver copper-phosphorus alloys
• Made in the USA

Compatibility

Designed for brazing copper-to-copper and copper-to-brass joints in HVAC, refrigeration, and plumbing applications.

Installation Notes

Brazing operations on refrigerant-carrying systems must be performed by licensed technicians in accordance with applicable mechanical and refrigeration codes. Always purge copper tubing with dry nitrogen during brazing to prevent internal oxidation scale. Shut off all refrigerant flow and depressurize the system before opening any joints. When joining copper to brass with this alloy, apply an appropriate brazing flux to the joint area before heating.
