Electroterni S.r.l. was incorporated in Terni in 1990 as a vertical integration of the former magnetic steel sector of Terni Steelworks.

Its business focuses on the production of laminations for power and distribution transformer cores, and it is directly connected to Nuova Eletrofer, a company located in Serravalle Scrivia that provided equipments and technology.

Following the recent acquisition of Magnetic S.p.A., a historical manufacturer of wound annealed cores, we can offer a full range of magnetic alloys, including silicon steel, and special magnetic alloys such as FeNi, nanocrystalline materials and very thin sheets suitable for medium and high frequencies. Thanks to a careful management of our raw materials warehouse and tight cooperation with steel producers, we can meet all customer requirements promptly.
