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 coper, 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
