Lucas Milhaupt 95177 Sil-Fos 15, 7 Rods, 15% Silver

Sil-Fos 15 is the preferred alloy for general copper-copper brazing; the phosphorous in the Sil-Fos family serves as a fluxing agent, no flux is recommended. Sil-Fos 15 is the best alloy to use when joining metals where close fit-ups cannot be maintained 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
