Fine white powder consisting a mixture of the potassium fluoroaluminate salts of the general formula K1-3 Al F4-6.
melting point range of 565°C to 572°C, below the melting temperature of 577°C of the Al-Si brazing alloy. The particle size lies in the range of 2 μm to 50 μm.
Simbon flux is non-hygroscopic and only very slightly soluble in water (0.2 % to 0.4 %). The flux does not react with aluminum at room temperature or at brazing temperature and only becomes reactive when molten (at least partially molten). The flux leaves a mainly water insoluble residue which need not be removed.
working range of 575-600°C
in accordance with DIN EN 1045 FL 20 , DIN 8511 F-LH2
