Description
Stay-Silv® 5% Silver Brazing Alloy – 28 Stick Tube
Stay-Silv® 5 is a 5% silver phosphorus-copper brazing alloy designed for HVAC, refrigeration, and general copper brazing applications. It provides dependable joint strength, smooth flow, and efficient capillary action for copper-to-copper connections.
With a moderate melting range, Stay-Silv® 5 allows for effective joint penetration while maintaining control during installation. This alloy is self-fluxing on copper, helping streamline the brazing process and reduce installation time.
Key Features
- 5% silver brazing alloy for copper-to-copper applications
- Cost-effective alternative to higher silver content alloys
- Self-fluxing on copper – no flux required for copper brazing
- Good flow and capillary action for strong joints
- Moderate melting range for controlled application
- Recommended joint clearance: 0.003"–0.006"
- Corrosion resistance similar to copper base metal
- Complies with EU REACH & RoHS directives
Applications
- Air conditioning and refrigeration piping systems
- Copper tubing and pipe brazing
- HVAC installation and service work
- Copper-to-copper and copper-to-brass connections (with flux)
Important Notes
- Flux not required for copper-to-copper brazing
- Flux required for brass or copper-to-brass applications
- Not recommended for steel or other ferrous metals
- Avoid use in environments exposed to sulfur or sulfur compounds
- Suitable for copper-nickel alloys up to 10% nickel
