Advancing solder manufacturing for a connected India

Saru Solder and Ishikawa Metals, Japan have joined forces to manufacture advanced, high-reliability solders within India — for electronics, automotive, aerospace, and renewable energy manufacturers.

Combining Japanese metallurgical precision with Indian manufacturing scale

Seven decades of Indian solder manufacturing paired with a century of Ishikawa's precision alloy engineering, now produced together within India.

About Saru Ishikawa

A new chapter

Saru Smelting Pvt. Ltd., a pioneer in non-ferrous metallurgy and soldering solutions in India, is glad to share the strategic collaboration of its company Saru Solder with Ishikawa Metal Co., a globally renowned manufacturer of premium soldering solutions based in Japan.

Saru Solder is India's pioneer manufacturer of a complete range of solders; it has been manufacturing solders since 1950. Their association with Ishikawa Metals, Japan goes back to 2010, when Saru Solder became Ishikawa's exclusive distributor of solder bars, solder wire, fluxes, SMT paste, and SEM materials in India.

Under this association, we will produce advanced, high-reliability specialized solders within India, combining indigenous manufacturing infrastructure with Ishikawa's century-long precision metallurgical formulation and engineering expertise.

The initiative directly addresses the soaring domestic demand for high-performance interconnect materials across India's rapidly expanding electronics system design and manufacturing (ESDM), automotive, aerospace, and renewable energy sectors.
