JO FLUX® started its journey in 1993 as a distributor and trading company for non-ferrous brazing alloys in India. In 1999, we started manufacturing industrial soldering fluxes at our Bhosari, Pune facility.
In 2003, we established a dedicated laboratory and R&D division and expanded into electronic soldering and brazing flux manufacturing in 2006. In 2010, we developed a manufacturing facility for inorganic chemistry raw materials at Khadakwasala, Pune.
In 2013, our Bhosari facility became dedicated to electronic soldering flux production. Later, in 2019, we introduced a new generation of brazing fluxes that are free from boric acid and borax.
With years of experience as a Silver Brazing Flux Trader, JO FLUX® continues to provide reliable welding, brazing, and soldering flux solutions for industrial applications.
Selecting the appropriate flux depends on several factors including base metal, filler alloy temperature, heating technique, production requirements, joint design, and post-brazing cleaning requirements.
