<p>A fine particulate flux, an aqueous flux preparation comprising this flux, a method for the manufacture of a coated part of aluminum, aluminum alloys, steel, copper or titanium using such flux, and a method for brazing parts of aluminum or aluminum alloys to parts of aluminum, aluminum alloys, steel, copper or titanium using such flux. The flux can be obtained by sieving, or it can be obtained by removing solids, e.g., in a cyclone, from the drying gases obtained when wet fluxes are dried, especially after their manufacture. Fine particulate flux increases the viscosity of flux preparations comprising the flux dispersed in water or an aqueous or liquid organic carrier.</p> |
