HZ-QJ208 fluxis a fine white powder consisting of a mixture of potassium fluroroaluminate salts which is non-corrosive and non-hygroscopic.
The flux of the highest quality and consistency is produced under stringent process tolerances and a variety of quality control procedures by us.
The flux has a melting point range of 560°C to 574°C, just below the eutectic temperature of the Al-Si brazing alloy.
Theparticlesizeliesintherangeof 1umto5um.
Duringthebrazingprocessthefluxdissolvestheoxidelayeronaluminumandallowthefiller metal to flow freely into the Hand Tools joints by capillary action.
After cooling, the flux residue remains on the surface as a thin adherent film and is non-corrosive and non-hygroscopic.
The flux does not require post brazing treatment of the joint area.
