ALUXCOR® 78/22 zinc-aluminum brazing filler metal has a non-corrosive and non-hygroscopic cesium flux core with a lower melting temperature and wider melting range than aluminum-silicon alloys. Its excellent strength and corrosion resistance makes it ideal for joining aluminum-to-aluminum or aluminum-to-copper or brass. It is free flowing with unequaled capillary attraction, ductility and penetration. Contains a cesium-fluoroaluminate (CsAlF) type flux in an 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. Complies with the EU Reach & RoHS directive.
