Sil-Fos 5 is a silver-copper-phosphorus alloy for copper-copper brazing but can also be used to join brass with an appropriate flux (e.g. Handy Flux, Ultra Flux). It is a more cost effective Ag-Cu-P alloy, though it does not penetrate deep joints easily.
Joins CU to CU (phosphorus serves as flux)
Joins CU to Brass (flux is recommended)
Lower cost alternative to higher silver content Ag-Cu-P alloys
Medium flow
Made in USA
Industry Applications:
HVAC/R refrigerant systems, air conditioning coils, evaporator coils
