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
