What Dexter Magnetic Technologies does

Dexter Magnetic Technologies is a U.S.-based private manufacturer of permanent magnets and custom magnetic assemblies, operating as a subsidiary of the Permag holding company since its 1951 founding. The company designs, engineers, and fabricates magnetic components across the full material stack — Neodymium Iron Boron (NdFeB), Samarium Cobalt (SmCo), Alnico, Ceramic Hard Ferrite, and bonded magnets — as well as electromagnets, magnetic couplings, MRI/NMR static field sources, biomagnetic separators, and specialty products such as the patented EraseTrack bulk eraser and Stelter Array dipoles capable of up to 3.0 Tesla uniform fields. Its products serve highly regulated end markets including defense, aerospace, medical devices, surgical robotics, semiconductor manufacturing, space, data storage, energy, and industrial applications.

Dexter operates from a 68,000 sq ft headquarters and manufacturing facility in Elk Grove Village, Illinois, with additional manufacturing in Torrance, California (via the 2022 MCE acquisition) and a European regional office in Freiburg, Germany opened in 2019. The company is AS9100D certified for aerospace (2017) and ISO 13485:2016 certified for medical devices (2018), with ISO 7 / Class 10000 cleanroom assembly capability supporting FDA/CE-compliant medical OEM programs. Under the Permag umbrella, Dexter has access to U.S.-produced rare earth materials via Electron Energy Corporation and, as of September 2025, a Solvay/LCM western rare earth supply partnership.

Revenue is generated through custom quote-based pricing on engineered-to-order magnetic assemblies and magnet materials, sold via a direct enterprise sales motion to OEM customers in regulated industries. Pricing varies by material, geometry, certification, and program lifecycle, typically structured as multi-year contracts. The 2026 Northrop Grumman Supplier Excellence Award and the 2022 facility doubling suggest ongoing capacity- and capability-led expansion. Revenue is not publicly disclosed; no funding rounds were identified beyond a 2021 Tinicum relationship, and the company remains privately held under Permag ownership.
