Fluoro aluminate aluminum brazing flux

In recent years, the NOCOLOK method has been widely applied in aluminum and its alloy brazing process. This product is the soldering agent used in the brazing process of the method.
Fluoride flux is also known as non - corrosive insoluble flux. It is used to brazing aluminum alloy and aluminum alloy with al-si alloy.
It is characterized by high activity at high temperature of brazing. It can remove the aluminum oxide film very well, so that the solder can be spread and moistened, and the brazing filler can be filled into the solder.
Under normal temperature, the glass-like residue after brazing is insoluble in water, non-absorbent and non-corrosive. It is completely inactive and is insoluble and no corrosive flux.
Especially in nitrogen protection brazing, the amount of flux is less, not cleaning after welding, easy to use, showing its strong superiority.
Main USES: in the aviation, spaceflight, automobile, train, chemical industry, household electrical appliances, tableware, etc have been widely used in the furnace under protective atmosphere of aluminium evaporator, radiator, condenser, cooler, heater core brazing, high-frequency heating under the bottom of the pot cover brazing stainless steel and aluminum brazing process such as waveguide.
With the development of technology and the development of industrial technology, the use of this flux will be more extensive.
The soldering flux is when it is used in the automatic brazing flux with distilled water or deionized water into the concentration of 3.5% to 5%, and stir evenly, make the soldering flux is used after suspension. Also can use distilled water or deionized water used after tune into a paste.

The fluxes of brazing temperature of 560 ℃ to 570 ℃, weld workpiece material for aluminum and its alloys, stainless steel and other materials.
