Stay-Silv® 15 is an industry-standard 15% silver brazing alloy widely used across HVAC, refrigeration, and general engineering applications. Designed for strength and reliability, this filler metal performs exceptionally well in joints where close fit-up is not possible, making it ideal for real-world installation conditions.
With a wide melting range, Stay-Silv® 15 allows for excellent gap-filling, capillary action, and build-up around joints, ensuring strong, leak-free connections even under thermal expansion and vibration.
Industry-standard 15% silver brazing alloy for consistent, high-quality results
Ideal for copper-to-copper and copper-to-brass brazing
Self-fluxing on copper, reducing the need for additional flux in many applications
Wide melting range enables gap filling, capping, and build-up
Excellent performance in vibration-prone and thermally stressed systems
Proven choice for HVAC and refrigeration pipework
Suitable for low-nickel copper alloys (up to 10% nickel)
Strong, durable joints with corrosion resistance similar to copper base metals
Complies with EU REACH & RoHS directives
HVAC and refrigeration systems
Air conditioning pipework
Copper plumbing and pipe joints
Marine and industrial copper systems
General-purpose brazing where joint fit-up is inconsistent
For copper-to-copper applications, the alloy is self-fluxing
For copper-to-brass, use a suitable brazing flux such as Stay-Silv® white flux
Not recommended for steel or ferrous metals due to limited joint ductility
Avoid use in environments exposed to sulfur or sulfur compounds, as phosphorus-containing alloys may degrade
Stay-Silv® 15 remains a go-to silver solder brazing rod for professionals who need reliability, flexibility, and strong joints in less-than-perfect conditions. Its ability to handle loose connections and dynamic service environments makes it a trusted solution across marine, HVAC, and industrial applications.
