Aluxcor 78/22 Flux Cored Brazing Alloy

Aluxcor 78/22 is a high-performance aluminum brazing alloy developed for joining aluminum to aluminum and aluminum to copper or brass components. It provides excellent joint strength and corrosion resistance, making it suitable for HVAC manufacturing and industrial brazing applications.

The alloy flows smoothly with strong capillary attraction, allowing effective penetration and ductile joints. It is supplied with non-corrosive and non-hygroscopic flux combinations that require no binder, enabling flexibility for different heating methods and operating conditions.

An improved round flux-cored ring design protects internal flux until proper pre-heating occurs, reducing flux burn-off and improving brazing consistency. The seam construction minimizes flux loss during transportation and handling while also helping rings remain securely positioned during installation.
