Brazing Flux 101
A chemical flux is commonly used with many braze filler metals. Proper fluxing is important because the flux absorbs oxides formed during heating and promotes the flow of filler metal. Fluxes are chemical mixtures that contain varying chemical components. The mixture is blended to ensure smooth application and adherence.
Ever wonder about the different flux types and where each is used?
