Aluminum Brazing Flux: A Crucial Component for Strong and Durable Joints

Aluminum Brazing Flux is a chemical compound specifically formulated to work with aluminum alloys. It is typically composed of a mixture of fluoride salts, such as potassium fluoride and sodium fluoride, along with other additives. When applied to the aluminum surfaces to be joined, the flux reacts with the oxide layer, breaking it down and forming a thin, protective layer. This layer prevents the aluminum from re-oxidizing during the brazing process, ensuring a strong and reliable bond. In addition to its functional benefits, aluminum brazing flux can also improve the appearance of the brazed joint. By preventing oxidation and promoting a smooth, even flow of filler metal, the flux can help to create a more aesthetically pleasing result.
