Aluminium Brazing Flux Powder is a high-activity, non-corrosive flux formulated to facilitate clean and efficient brazing of aluminum and its alloys. Composed primarily of fluorides and chlorides of alkali and alkaline earth metals, this powder flux effectively removes aluminum oxide layers and promotes wetting of the brazing filler metal. It enables strong, void-free joints at typical brazing temperatures ranging from 500°C to 600°C. The fine powder form allows for easy application by brushing, dipping, or spraying, and is compatible with various brazing methods including torch, furnace, and induction brazing. Ideal for automotive heat exchangers, HVAC components, and aluminum tubing assemblies, this flux ensures improved flow characteristics, joint integrity, and minimal residue. Post-brazing cleaning is recommended to prevent long-term corrosion, especially in moisture-prone environments.
