15% Silver Brazing Rods, 16 Sticks Solder Phos Copper Brazing Welding Rods — Open-Box, 20% Off

【High-Performance BCuP-5 Alloy】Each brazing rod is crafted from premium 15% silver (Ag) with a balanced Copper-Phosphorus (BCuP-5) composition, our welding rods deliver exceptional fluidity, high tensile strength, and superior thermal stability. This ensures seamless, robust joints for critical applications.

【Optimized Thermal & Flow Specs】These brazing rods feature a wide brazing range with a Solidus of 1193°F (645°C) and Liquidus of 1472°F (800°C). The enhanced capillary action allows the alloy to penetrate tight joint clearances (0.002"–0.006"), ensuring deep fusion and reducing the risk of cold solder defects.

【Self-Fluxing Properties】The package contains 16PCS 15% silver brazing rod, suitable for welding, soldadura, and industrial maintenance. For copper-to-copper brazing, the phosphorus acts as a self-fluxing agent, eliminating the need for additional flux. Tip: Always clean surfaces thoroughly before brazing.

【Versatile Professional Applications】Specifically designed for the HVAC and refrigeration industry, these welding rods are ideal for joining copper-to-copper, copper-to-brass, and copper-to-steel (flux recommended for dissimilar metals). Perfect for the connection and repair of air conditioners, refrigerators, compressors, and plumbing systems.

【Aluminum Foil Vacuum Packaging】Our 15% silver brazing rods come in airtight aluminum foil vacuum bags that lock out moisture and oxygen. This prevents oxidation of silver and copper, preserves flux activity, and ensures the solder sticks remain ready for use even after long-term storage.
