Water-soluble aluminum flux can be used together with the aluminum based brazing filler materials to braze aluminum and aluminum
Aluminium welding flux powder:
Availability | Water-soluble aluminum flux can be used together with the aluminum based brazing filler materials to braze aluminum and aluminum alloy, using manual torch brazing and automatic torch brazing | |
Physical description | White powder, granularity ≤ 150 um, density: 1.3-1.4 g/cm3. | |
Components | Alkali metals, alkaline-earth metal chlorides, fluoride, and active agent. | |
Standard | JB/T6045-92, Fluxes for Brazing, Zhuang, Hongshou | |
Packaging | 500 g/box, 20 kg/carton, 500 g/bag, 40 kg/carton, 30 kg/drum, 250 g/box, 20 kg/carton. | |
Operation | In advance, properly place the brazing filler metal on the brazing joint which will be heated together with the work pieces. In the process of manual torch brazing, firstly, the brazing wire needs to be tipped with the flux Then, after the work pieces are heated to the brazingtemperature,the brazing wire is manually handled to keep close to the brazing joint. The wires are evenly heated by the outer flame from the Multiple-holesbrazing torch, To protect the metallic materials, the flame should be placed at the proper distance away from the wires to avoid the oxidation of the work pieces, producing high-quality brazing seams. | |

Post treatment | The residue of the Water-soluble Aluminum Flux attached on the work pieces is corrosive which should be cleaned timely. | |
Several methods of post treatment | ||
1. Scrub the joint in the water with 50-60C. 2. Complicated work pieces can be merged into cold water after the solidification of the filler metal. The residue can fall off the surfaces because of thesudden boiling of water. Partial component in the residue can be dissolved into the water. In this method, the temperature difference between the cold water and the work pieces should be cautiously controlled to prevent the shaping and cracking of the work pieces. 3. Use 30 g/l concentrated oxalic acid, 15 g/l concentrated sodium fluoride, and 30 g/l concentrated #601 detergent water solution washing. Keep the temperature to be 70-80C. 4. Use phosphoric acid with volumetric fraction of 5%, and chromic anhydride water solution with 1% mass concentration to wash at 82C. 5. After being dipped in hot water, merge the work pieces in to the nitric acid with volumetric fraction of 10% and hydrofluoric acid with volumetric fraction of 0.25% for 2-3 min. |
