SIMBON / TECHNICAL NOTESFlux selection depends on the base metal, filler alloy and heating method. Flux helps remove remaining oxides and limit oxidation during heating.
The active range of the flux must cover melting and flow of the alloy. The initial melting point alone is not enough: full-flow temperature and heating duration also matter.
A flux suitable for a small component may therefore be unsuitable for a longer heating cycle.
