DETAILS
Aluxcor® 4047 F15.1 flux-cored brazing wire is designed for manual and semi-automatic aluminum flame brazing. A common application is brazing HVAC aluminum components including return bends, headers, tube assemblies, and distributors. 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. Aluxcor® 4047 is available with different flux compositions. 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. Complies with the EU Reach & RoHS directive.

| Recommended Flux | No flux required as this product has a potassium fluroaluminate salt type flux internal core. The core percentage and dimensions are calculated to deliver optimum flux release and braze joint protection during heating. Post braze residue from this flux is non-corrosive, so removal is typically unnecessary. |
