Reliability in Every Alloy: Sil-Fos® – The HVAC/R Professionals Trusted Choice for Decades
For nearly a century, Sil-Fos® has reigned supreme as the go-to silver brazing alloy, especially revered among HVAC/R contractors. Pioneered and patented in 1931 by Handy & Harman (HNH), Sil-Fos is a unique amalgamation of silver (Ag), copper (Cu), and phosphorous (P) that promises consistent, high-quality joints while optimizing materials and significantly slashing time and associated process costs. One standout feature of this alloy is its capability to join copper to copper seamlessly without the need for flux, thanks to the phosphorous content that reacts with copper oxides, ensuring an immaculate surface for brazing. Today, Sil-Fos still stands as a testament to Lucas Milhaupt and Handy & Harman’s commitment to quality, resilience, and innovation. This potent brazing solution has not only played a pivotal role in wartime machinery repair during World War II but continues to be the top-tier choice for HVAC/R professionals today, promising robust, flux-free brazed joints every time. As distributors, manufacturers, and contractors search for reliability and excellence in brazing solutions, Sil-Fos remains an unbeatable choice, a legacy product from Lucas Milhaupt that combines history with unparalleled performance.
