Welcome to the S.A. Day Buffalo Flux Facility, Johnson Mfg. Co. Web Site

The S.A. Day Buffalo Flux Facility is a leading manufacturer of brass and copper soldering and brazing fluxes, custom fluxes and aluminum brazing flux for the automotive heat exchanger industry. We are the premier supplier of top-quality copper, brass and aluminum brazing fluxes and soldering fluxes.

For close to 40 years, S.A. Day has been supplying world-wide manufacturers of radiators, heater cores, condensers, evaporators and oil coolers with quality custom fluxes: brass, copper and aluminum. We got our start providing flux for soldering brass to copper by developing the bromide based flux. As the heat exchanger market changed to aluminum, we developed non-corrosive aluminum brazing fluxes. If you have a flux question or are having a soldering or aluminum brazing problem, give our technical experts an opportunity to be of service.

Flux is not all we sell. We offer a complete line of products and technical expertise to assist you in solving your soldering and aluminum brazing problems.
