Located in Conway, South Carolina, Metglas, Inc. is the world’s leading producer of amorphous metal ribbon and components used in the production of electrical distribution transformers, high frequency magnetic components for power electronics, material for anti-theft tags, brazing alloys and solder. In 2003, Metglas, Inc. became a subsidiary of Hitachi Metals America, Ltd.  The integration of technical resources has focused on the development of new applications to enable a broader range of technical solutions for its customers.

FINEMET® common mode choke cores are made of a nanocrystalline soft magnetic material that Hitachi Metals developed as a world first. Conduction noise often causes serious malfunctions in onboard electronic components. With more electronic components being installed in cars, conduction noise is becoming a more serious issue for safe driving. Compared to conventional products with Mn-Zn ferrite cores, FINEMET® has higher magnetic permeability and magnetic flux density. It results in realizing size and weight reductions of automotive electronic components.

Applications include hybrid electric vehicles (HEV), electric vehicles (EV) and plug-in hybrid electric vehicles (PHEV).
