Ferrotec USA

Ferrotec USA wishes that the magnetic force be with you. A subsidiary of Japanese specialty materials maker Ferrotec, the company makes fluids that, when controlled with a magnetic force, can be used for sealing, sensing, lubrication, and heat transfer. Known as ferrofluidics, these liquids are used by makers of audio speakers and lighting -- General Electric is a major customer -- and in its own engineered products. Ferrotec USA's sealing devices are used for making semiconductors and in oil and chemical production. In 2010 Ferrotec USA acquired Integrated Materials and its SiFusion process for manufacturing poly silicon furnaceware. The company's US locations are in California and New Hampshire.
