Description
Lucas-Milhaupt 95150 Sil-Fos 15 Silver-Copper-Phosphorus Alloy
28 Sticks/Tube
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.
Features
- 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
Typical Industry Applications:
HVAC/R refrigerant systems, air conditioning coils, evaporator coils
