Valued Pack for Cost Efficiency:Each tube of Bluefire brazing rods contains 20 sticks, each 14" long, totaling 0.5 pounds in weight, offering great savings for projects requiring Silver Brazing. These Filler Brazing Rods are essential for professionals and DIY enthusiasts needing high-quality welding rods at an affordable price. The solder stick design provides excellent value, making it ideal for various applications, including Air Conditioning Refrigerators and Storage HVAC systems.

Superior Performance Characteristics:These brazing rods exhibit a solidus temperature of 1189°F (643°C) and a liquidus temperature of 1419°F (771°C), with a fluidity rating of 3. The recommended joint clearance of 0.003" to 0.006" ensures that the welding rod delivers superior performance, with the silver content significantly enhancing fluidity. This allows the copper solder to flow into small gaps, resulting in stronger, tougher joints and reducing brazing time.

5% Silver Bearing Welding Rods:The Bluefire brazing alloys rods, classified as USA AWS A58 Class BCuP-3, are composed of 4.8-5.2% silver (Ag), 6.5-7.0% phosphor (P), and the rest copper (Cu). These silver solder rods are designed for optimal performance when used with Bluefire JFB-102S brazing flux. The inclusion of silver solder wire enhances copper solder applications by improving wettability and reducing melting temperatures, making these rods perfect for Copper Phosphor Brazing.
