Superior Flux & Mfg. Co.

Since its founding in 1932, Superior Flux has been focused on flux. In the many years we’ve been formulating flux and solving problems for customers, we’ve learned a lot about fluxes and the processes in which they are used. We carry what is perhaps the broadest range of fluxes in the world. We make flux for soldering, brazing and welding. Our soldering line includes fluxes that can stand up to the rigors of industrial soldering applications, and fluxes that meet the tight specifications of electronics soldering applications. We are conducting extensive research in exciting new areas of aluminum soldering. Our brazing fluxes include general purpose silver brazing paste, high temperature carbide brazing fluxes, aluminum brazing fluxes and fluxes for other specialty applications. We also offer a full range of welding fluxes.
