Sil-Fos has been the preferred silver brazing alloy for HVAC/R contractors since it was patented in 1931. Sil-Fos alloys combine silver (Ag), copper (Cu), and phosphorous (P) to produce consistent, quality joints while saving on materials plus reducing time and process costs.
Sil-Fos® alloys have become popular in the HVAC/R and plumbing industries because of the ability to join copper to copper without flux. No flux is necessary with Sil-Fos alloys; the phosphorous in the Sil-Fos family of products reacts with the copper oxides to form phosphorous pentoxide and cleans the surface.
HVAC/R contractors have trusted Sil-Fos and Lucas Milhaupt for seamless, strong joints in the field for nearly ninety years.
