Lucas-Milhaupt Sil-Fos 15 95150 Brazing Rod, For Copper, Brass, Bronze, Silver, Copper, Phosphorus, 1/20" (Thickness) Diameter, 20" Length, Gray Finish, 1300-1500 °F, 30,000 - 35,000 lbs/In2 (Copper), 35,000 - 40,000 lbs/In2 (Brass) Tensile Strength

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.This alloy was developed primarily for use on copper but its use has extended to other nonferrous copper base alloys. It is used extensively on refrigeration units, air conditioning apparatus, electrical conductors, copper and brass pipe fittings, and other copper and brass equipment.

Lucas-Milhaupt Brazing Rod, Model: Sil-Fos 15, For Copper, Brass, Bronze, Silver, Copper, Phosphorus, 1/20" (Thickness) Diameter, 20" Length, Gray Finish, 1300-1500 °F, 30,000 - 35,000 lbs/In2 (Copper), 35,000 - 40,000 lbs/In2 (Brass) Tensile Strength, Bcup-5, 28 Pieces (1 lb) Container Size, Tube

• Features a self-fluxing property when joining copper to copper due to its phosphorus content.
• Requires the use of flux when brazing copper to brass or bronze alloys.
• Provides the highest joint ductility within the Sil-Fos family.
• Suitable for joints where fit-up may be marginal or where fillet build-up is needed.
• Penetrates well into long shear depths, despite a slower flow characteristic.
• Widely used in HVAC/R applications for refrigerant systems, AC coils, and pipe fittings.
• Meets AWS A5.8/A5.8M BCuP-5 specifications.
• Manufactured in the USA.
