The flux cored concept introduces flux inside a brazing wire for one single product ready to use.


  • Simplifies the brazing process by eliminating separate flux and increases productivity.
  • Produces stronger joints of higher quality due to concistent application of alloy and flux and enhances process control.
  • Reduces flux residues in the production facility and post cleaning due to minimal flux exposure. Flux residues are between 4 to 10 times less than separate flux operation but still enough to give a high quality joint. Gives less contamination on parts, machines and fixtures that will lead to cost savings in maintanace.
  • Less mass to heat compared to solid material, leads to shorter melting time, better productivity and base material is less affected by the temperature.
  • Less filler metal is used (typically 20%)
  • Optimal use together with induction heating system to get the most optimized brazing result every time

Environmetal advantages

  • No resine(binder) inside compared to flux coated material leads to less fumes for the operator. 100% flux inside.
  • Flux inside the rod – no more pfysical contact with chemicals by the operators
  • No more flux waste and residues on machines, fixtures and other equipment, production facility will be cleaner and healthier

Equal joints brazed by separate alloy and flux as well as flux cored material shows us there is less voids and flux inclusions. Ultra sound tests have also been made to confirm that flux cored material will give >5% better degree of filling. This can be of extra importance if the depth of the joint is too big. This is common in some industries where a standardized part is used.

  • The range of filler metals include most silver brazing alloys as well as 4 different aluminium brazing alloys
  • Different types include wires, rods, rings and wire segments/preforms (flat, round and oblong)
  • Standard dimensions from 1,0-3,0mm, others on requests
  • Various types of inside flux depending on application
