Aluminum Brazing Flux
What is aluminum brazing flux?
Aluminum Brazing Flux is a chemical aid specially formulated for the brazing of aluminum alloys. Its essential functions are to remove the tenacious surface oxide film on aluminum, prevent re-oxidation during brazing, and reduce the interfacial tension between the filler metal and the base material, thereby enabling the filler to spread and wet the surface so that a strong, sound joint can be formed.
Aluminum instantly forms a dense Al₂O₃ film in air—only 2–10 nm thick, yet extremely hard and with a melting point of 2,050 °C, far above the 660 °C of the aluminum matrix. At brazing temperature this film neither melts nor breaks down, blocking the filler metal from reaching the base metal. The central job of an aluminum brazing flux is to “break” and “bar” this oxide layer.
Aluminum brazing flux is the specialty molten salt that “breaks the oxide film, prevents re-oxidation, and promotes wetting” during aluminum brazing—the unsung hero that enables strong, leak-tight aluminum joints.

Advantages of Brazing Flux Cleaners
Aluminum Brazing Flux
1. Ensures homogeneous dispersion of KAlF₄ powder within the stirred aqueous medium.
2. Suppresses flux-solution sagging, thereby preventing crystallization defects.
3. Generates zero carbonaceous residue during high-temperature brazing or drying cycles.
4. Promotes uniform, planar deposition of KAlF₄ on aluminum substrates.
5. Mitigates cold-joint formation attributable to inadequate degreasing or insufficient flux flow.
6. Provides integrated detergency that eliminates surface oil films, enhancing post-braze metallic luster.
7. Remains gel-free throughout the process, preserving final component aesthetics.
Industrial-Grade Precision Cleaner
1. **Corrosion Inhibition**
Targeted antioxidant additives form a micro-protective film during cleaning, eliminating flash rust and pitting on freshly exposed metal.
2. **Dead-Zone Penetration**
Ultra-low surface tension (<25 mN·m⁻¹) drives the fluid into blind holes, capillaries and lap joints, lifting entrenched soils without leaving inaccessible residues.
3. **Luster Restoration**
Chelating polishers remove free-iron contaminants and oxide blooms, restoring a specular, mirror-like finish to previously dulled stainless steel.
4. **Oil-Film Stripping**
Rapidly solubilizes hydrocarbon corrosion inhibitors yet retains base-metal integrity, delivering a water-break-free surface ready for welding, coating or assembly.
5. **High-Efficiency Economy**
Effective at 2–4 % v/v; high soil-loading capacity extends bath life 3–4× versus conventional cleaners, cutting overall process cost by up to 40 %.
6. **Rinse-Free Tracelessness**
Clean-water rinse yields zero watermarks, streaks or secondary contamination, ensuring seamless downstream processing.
Cleaning Waste Liquid Treatment Plan
Wastewater generated by metal parts cleaning contains metal ions, oil, and some precipitated pollutants, requiring treatment to meet environmental standards. Our company utilizes on-site treatment methods, including adsorption, filtration, flocculation, sedimentation, oxidation, and pH control, to remove oil, suspended solids (SS), heavy metal ions, and reduce organic matter (COD) content to meet national environmental standards.
1. Adsorption (Oil-Water Separation): Activated carbon or cotton wool is used to absorb and remove suspended oil from the wastewater surface.
2. Suspended Solids Treatment: A filter is installed at the wastewater outlet to remove heavier suspended solids (SS).
3. Flocculation and Sedimentation: After filtration, the wastewater still contains fine particles and colloids. Polyacrylamide, a non-toxic and environmentally friendly organic polymer flocculant, is used to amplify and precipitate the fine particles. This process also adsorbs organic matter and COD in the wastewater.
4. Oxidation: After flocculation and sedimentation, the wastewater is decolorized with sodium hypochlorite to further reduce the COD content.
5. pH Adjustment: After the above treatment, the SS, COD, and metal ion levels in the wastewater are significantly reduced. Use hydrochloric acid to neutralize the wastewater pH to between 6 and 9 (using high-precision pH test paper or a pH meter with an accuracy of 0.1), meeting the national environmental protection secondary emission standards.
