600 Powder Flux Brazing Flux

600 Powder Flux is a highly active brazing flux formulated for general-purpose use with bronze alloys such as Welco 15. It supports clean and reliable brazing on steels, cast irons, and copper-based alloys. The flux may be used in dry form or mixed with water to create a paste, depending on application preference.

During brazing, the flux promotes proper metal flow while reducing oxidation and impurities. After the process, residues can be removed easily with hot water, leaving bright, clean, and porosity-free brazed joints suitable for professional and industrial applications.
