Discover Aluminium Brazing Flux Powder for strong, clean, and durable metal joints. Ideal for HVAC, automotive, and industrial brazing applications.
When it comes to joining aluminium components, one of the biggest challenges is overcoming the oxide layer that naturally forms on the metal’s surface. This is where Brazing Flux Powder for Aluminium plays a critical role. Specially designed to ensure strong and reliable joints, this flux is widely used in industries such as HVAC, automotive, and manufacturing.
Brazing flux powder is a chemical cleaning and protective agent applied during the brazing process. Aluminium surfaces naturally oxidize, which makes soldering or brazing difficult. Flux powder dissolves this oxide layer, prevents further oxidation, and allows the filler metal to flow smoothly, creating a strong and leak-proof joint.
Ensures clean metal surfaces by dissolving aluminium oxides.
Promotes capillary action for even distribution of brazing filler metal.
Produces durable, leak-proof, and corrosion-resistant joints.
Formulated to perform in the high-heat range required for aluminium brazing.
Suitable for torch brazing, furnace brazing, and induction brazing.
HVAC & Refrigeration Systems – For joining aluminium tubes, evaporators, and condensers.
Automotive Industry – Used in radiators, heat exchangers, and fuel systems.
Aerospace & Marine – Ensures reliable bonding of lightweight aluminium components.
General Fabrication – Ideal for aluminium frames, piping, and structural assemblies.
Improves Bonding Efficiency – Ensures stronger and longer-lasting joints.
Reduces Defects – Prevents porosity, leaks, and weak welds.
Saves Time & Cost – Clean brazing reduces rework and repair.
Increases Durability – Joints resist corrosion and withstand pressure.
Clean the Surface: Remove dirt, grease, or heavy oxides.
Apply Flux: Coat the joint area with an even layer of brazing flux powder (sometimes mixed with water or binder into a paste).
Heat the Joint: Use the appropriate brazing method (torch, furnace, or induction).
Apply Filler Metal: Allow it to flow evenly across the joint.
Cool & Clean: Remove any remaining flux residue after brazing.
Q1: Can I use aluminium brazing flux powder on copper or steel?
No, it is specially formulated for aluminium. Different metals require different fluxes.
Q2: What filler metals are used with this flux?
Typically, aluminium-silicon (Al-Si) or zinc-aluminium based filler alloys are used.
Q3: Is flux residue harmful?
Residue should be cleaned after brazing as it may cause corrosion if left on the joint.
