We understand that flux behaviour is important to anyone brazing regularly. Why not test out one of our fluxes?
When brazing aluminium alloys in air it is necessary to use a brazing flux.
Three general formulations of flux are in regular use:
VBC Group can supply each of these formulations depending on the requirements of the application.

|---|---|---|---|---|
| Meta-Braze™ ALC 31 Flux Paste | 550-650 | FL10 | ViewMeta-Braze™ ALC 31 Flux PasteMeta-Braze™ ALC 31 is an aluminium brazing flux paste formulated for brazing of aluminium using an aluminium-silicon brazing alloy such as Meta-Braze Al 112 / BAlSi-4. It is suitable for automotive and aerospace applications and for the manufacture of aluminium heat exchangers. Downloads× | A general purpose aluminium brazing flux paste with good flux activity. Flux residues need to be removed after brazing. |
| Meta-Braze™ ALC 31 Flux Powder | 550-650 | FL10 | ViewMeta-Braze™ ALC 31 Flux PowderMeta-Braze™ ALC 31 Flux Powder is a highly active halide containing flux suitable for brazing of aluminium alloys in air with a torch, fixed burners or induction brazing heating methods and utilising an aluminium-silicon braze such as Meta-Braze™ AL 112 (4047 / 88:12). Flux residues are corrosive and must be removed after brazing by washing with hot water. Downloads× | A general purpose aluminium brazing flux powder with non-corrosive residues |
| Meta-Braze™ ALNC 21 Flux Powder | 570-660 | FL20 | ViewMeta-Braze™ ALNC 21 Flux PowderMeta-Braze™ ALNC 21 Flux Powder is a fluoride based flux suitable for brazing of aluminium alloys in a furnace or with a torch and utilising an aluminium-silicon braze such as Meta-Braze™ AL 112. Flux residues are non-corrosive and cannot be easily removed. Downloads× | A general purpose aluminium brazing flux powder with non-corrosive residues |
