Our Industry Experience

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.
