The SIL-FOS 15 is a versatile brazing alloy ideal for general-purpose copper joining in HVAC/R applications. Its composition, rich in copper and containing 15% silver, is engineered for creating strong connections in refrigeration units, AC coils, and copper pipe fittings.This alloy is self-fluxing on copper-to-copper joints due to its phosphorus content, simplifying the brazing process. While well-suited for joints where fit-up may be marginal, a separate flux is recommended when joining copper to brass to ensure a sound connection.
- Self-Fluxing: The phosphorus content acts as a fluxing agent for copper-to-copper brazing, simplifying the process and eliminating the need for a separate flux.
- Versatile Application: Designed for joining copper to copper or copper to brass, making it ideal for refrigeration units, air conditioning systems, and electrical conductors.
- High Ductility: Offers the highest joint ductility in the SIL-FOS family, providing strong, durable connections that can withstand vibration and stress.
- Controlled Flow: Features a slower flow that allows for fillet build-up and penetrates well into long shear depths, making it suitable for joints with marginal fit-up.
- AWS Certified: Conforms to AWS A5.8/A5.8M specifications under the BCuP-5 classification, ensuring consistent quality and performance.
