OVERVIEW

Premium Silvaloy 15 Brazing Rods – 25lb Bulk Package

For professional contractors and industrial fabrication shops requiring high-volume brazing solutions, the Lucas-Milhaupt Silvaloy 15 in a 25lb package offers both quality and economy. This premium filler metal is a silver-copper-phosphorus alloy designed for joining copper and copper alloys. With a 15% silver content, Silvaloy 15 is widely recognized as the industry standard for applications requiring high reliability, such as HVAC installation, refrigeration repair, and plumbing systems. The rods measure 0.094 inches in diameter and 36 inches in length, providing a substantial amount of material per rod to minimize downtime during long brazing sessions.

One of the primary benefits of using Silvaloy 15 is its versatility and ease of use. When joining copper to copper, this alloy is self-fluxing, meaning you do not need to apply a separate flux paste. The phosphorus contained within the rod acts as a fluxing agent when heated, cleaning the metal surface and allowing the alloy to flow smoothly into the joint. This feature significantly speeds up workflow and reduces consumable costs. For applications involving brass or bronze, a separate flux is required, but the rod performs with equal excellence, creating strong, leak-proof seals that stand the test of time.

The 25lb bulk packaging is specifically tailored for high-consumption environments. Rather than purchasing small tubes or individual pounds, this bulk option ensures your shop is stocked for major projects. The rods are manufactured to strict tolerances, ensuring consistent melting behavior and flow characteristics from the first rod to the last. Whether you are repairing air conditioning units, installing medical gas lines, or fabricating heat exchangers, Silvaloy 15 provides the ductility and strength needed for critical connections.

Choosing Lucas-Milhaupt means choosing a legacy of brazing excellence. Silvaloy 15 is engineered to bridge gaps better than lower-silver alternatives, making it forgiving on joints where the fit-up isn't perfect. Its corrosion resistance and electrical conductivity make it a top choice for electrical equipment manufacturers as well. Invest in the best for your brazing operations with this substantial supply of high-grade filler metal.

FAQ

If you are brazing copper to copper, no flux is required because the phosphorus in the rod acts as a fluxing agent. However, if you are brazing copper to brass or bronze, you must use a suitable flux (like Handy Flux) to prevent oxidation.

No. Phosphorus-bearing alloys like Silvaloy 15 should not be used on ferrous metals (steel, iron) or nickel alloys. The phosphorus reacts with iron to form brittle compounds that will cause the joint to fail.

This rod is classified as BCuP-5 under the AWS A5.8 standard.

Silvaloy 15 has a solidus temperature of 1190°F (643°C) and a liquidus temperature of 1475°F (802°C).

The 15% silver content provides significantly better ductility and vibration resistance compared to lower silver alloys. It is less brittle and better suited for systems that experience movement or thermal expansion.

The exact count varies slightly by batch, but a 25lb package of 0.094" x 36" rods contains a substantial quantity, typically calculated by weight rather than count for bulk industrial use.

Yes, Silvaloy 15 is cadmium-free and generally suitable for potable water systems, but you should always check local plumbing codes to ensure compliance.

For optimal capillary action and strength, a joint clearance between 0.002" and 0.005" is recommended.
