MMG's beginnings go back over 70 years as several different operating companies. The Neosid family of companies began manufacturing magnetic materials in the United Kingdom in 1936. They expanded their operations into Toronto, Canada in 1952 and Lilyfield, Australia in 1956. The Port Chester, New York Krystinel Corporation founded in 1954 was acquired by the UK based Magnetic Materials Group (MMG) in 1989. In 1990, the Group also acquired the magnetic interests of Salford Electrical Instruments (SEI). In 1974, the Chennai based EID Parry India Limited, a subsidiary of the Murugappa Group, with the assistance Siemens, began the operation of a soft ferrite plant in Chennai, India. This facility was later acquired by the TT Group in 1997.

The UK based TT Group, now known as TT electronics, acquired MMG in 1992. TT electronics plc is a focused, global electronics company supplying the world’s leading manufacturers in the automotive, telecommunications, computing and industrial electronics markets.
