Sil-Fos 5 is a silver-copper-phosphorus alloy developed primarily for copper-to-copper brazing, where its phosphorus content allows it to be self-fluxing. It can also be used to join brass or other nonferrous copper-base alloys with an appropriate flux (e.g., Handy Flux, Ultra Flux).This alloy serves as a more cost-effective alternative to higher silver content Ag-Cu-P alloys, although it may not penetrate deep joints as easily. It is widely used in HVAC/R applications such as refrigeration units, air conditioning apparatus, electrical conductors, and copper or brass pipe fittings.
