Harris® 4047 F15.1 0.062 Dia x 20" Aluminum Flux-Cored Braze Filler Metal comes in a 1/2 lb tube. It is designed for manual and semi-automatic aluminum flame brazing. The flux-core eliminates the need for a separate flux application and the core cross section is designed to release a measured amount of flux into the capillary. This ensures good oxidation protection and suitable capillary fill by the melted aluminum metal. This product has a 15.1 flux composition. Formula 15.1 is a potassium fluroaluminate salt with a melting range of 1049 ° - 1061° F, (564° - 572°C). The flux chemistry and ratio is designed to provide brazing characteristics engineered for specific applications. This composition is non-hygroscopic, so post braze flux residue does not need to be removed. Common applications include brazing HVAC aluminum components such as return bends, headers, tube assemblies, and distributors. Conforms to the EU Reach and RoHS directive.
