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.
