Harris Products Group, ZN78CW09420POP, Brazing Alloy, Zinc-Aluminum; Cadmium-Free, Flux-Cored, 0.003-0.005 in Joint Clearance

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.

Features

• Strict flux percentage tolerance ensures that the flux is consistent throughout the wire for repeatable high performance flow of the alloy
• ZN78 cadmium-free zinc-aluminum flux-cored brazing alloy
• A good choice for joining aluminum alloys of the 1000, 3000 and 6000 series
• Used to join aluminum-to-copper
• Complies with the EU Reach & RoHS directive
• Has a non-corrosive and non-hygroscopic cesium flux with no flux binder
• Lower melting temperature and wider melting range than aluminum silicon alloys
• Proprietary custom flux blends available for customer specific applications
• Core design releases the flux only after sufficient preheating, so both the flux and alloy flows at the right time into the capillary
