With excellent strength and corrosion resistance for joining aluminum-to aluminum or aluminum-to-copper or brass. Free flowing with unequaled capillary attraction, ductility, and penetration. Our ALUXCORTM zinc aluminum alloys also have non-corrosive and non-hygroscopic cesium flux with a lower melting temperature and wider melting range than aluminum silicon alloys.

ALUXCOR 4047 has four different non-corrosive and non-hygroscopic flux combinations with no binder to fit your customer specific heating applications. The different formulas flux’s release at increasing speeds in order from 15.1 being the slowest, to 15.4 being the fastest. The 15.3 formula is our most common for hand brazing applications but Harris now offers different formulas to best optimize flux release in controlled auto brazing heat applications.


  • Wide variety of wire diameter in spools and cut lengths in imperial and metric sizes
  • Preforms
  • Rings
  • Return bends and Crossovers
  • New round flux cored ring design
  • Protects the flux inside the wire until proper pre-heat which helps prevent silicon erosion from excess flux burn off on the tube
  • Seam prevents flux loss during shipping, loading onto the return bends, and in wire feed applications
  • Helps with return bend ring retention to prevent rings from moving or falling off return bends and crossovers
  • Core design releases the flux only after sufficient preheating so both the flux and alloy flows at the right time into the capillary
  • Proprietary custom flux blends available for customer specific applications 
  • Strict flux percentage tolerance ensures that the flux is consistent throughout the wire for repeatable high performance flow of the alloy
  • We only use non-corrosive and nonhygroscopic flux with no flux binder
  • In house manufacturing
  • Capability of manufacturing wire, flux cored rings, ring loaded return bends which helps lower costs and shorten the supply chain
  • Residential HVAC manufacturers
  • Fabricated Parts Manufacturers
  • Coil Manufacturers
