A brazing chemical flux is often used with many braze filler metals. Fluxes are chemical mixtures that contain varying chemical components, and is blended to ensure a smooth application. It is important to have proper fluxing because the flux absorbs oxides formed during heating as well as it promotes the flow of filler metal. It is available in White Flux, AMS 3410 and Black flux, AMS 3411.
