SIL-FOS 15
Product Overview
Sil-Fos 15 is the preferred alloy for general copper-copper brazing; the phosphorous in the Sil-Fos family serves as a fluxing agent on copper, so no flux is recommended. Sil-Fos 15 can be used with joints where fit up is marginal and is well suited for use in refrigeration applications.
Joins CU to CU (phosphorus serves as flux)
Joins CU to Brass (flux is recommended)
Highest joint ductility of entire Sil-Fos family
Allows for fillet build up
Slow flow but penetrates well into long shear depths
Made in USA
Industry Applications:
HVAC brazing
HVAC/R refrigerant systems, air conditioning coils, evaporator coils.
