Find a SIL-FOS® Reseller

We are pleased to offer our most popular brazing and soldering materials, in their most common forms. SIL-FOS®, developed and patented by Handy & Harman in 1931, is the original copper/phosphorous brazing alloy used by thousands of manufacturers and contractors in the HVAC&R industries.

Available either in bulk or pre-packaged lots are filler metals for brazing copper-based alloys (SIL-FOS®), steels, stainless, etc. (SILVALOY® and EASY-FLO® Alloys), as well as low temperature, lead-bearing (SOLDERITE™) and no-lead solders (SILVABRITE®). These materials are available through our distributor network, or if you are in an area that is not served by a distributor, we can ship directly to you the product you require (some minimums may apply).
