Product Description
Water-soluble aluminum flux 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 ≤ **0 um, density: 1.**1.4 g/cm3. Components:
Alkali metals, alkaline-earth metal chlorides, fluoride, and active
agent. Standard: JB/T******2, Fluxes for Brazing, Zhuang, Hongshou
Packaging: **0 g/box, *0 kg/carton, **0 g/bag, *0 kg/carton, *0
kg/drum, **0 g/box, *0 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. Preparation: In

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 ****0˚C. 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 *0 g/l concentrated oxalic acid, *5 g/l
concentrated sodium fluoride, and *0 g/l concentrated #**1
detergent water solution washing. Keep the temperature to be
****0˚C. 4. Use phosphoric acid with volumetric fraction of 5%, and
chromic anhydride water solution with 1% mass concentration to wash
at *2˚C. 5. After being dipped in hot water, merge the work pieces
in to the nitric acid with volumetric fraction of *0% and
hydrofluoric acid with volumetric fraction of 0.*5% for **3 min.
