Magnetic Metals

What Magnetic Metals does

Magnetic Metals Corporation, founded in 1942 in Camden, New Jersey and now headquartered in Cherry Hill, NJ, is a U.S. manufacturer of precision magnetic components — primarily tape wound toroidal cores (TWTC), tape wound cut cores (TWCC), and associated assemblies — for mission-critical power and signal applications. The company claims the broadest soft magnetic materials portfolio in the industry (amorphous alloys, nanocrystalline, cobalt-iron, multiple nickel-iron grades including Supermalloy and Supermendur, plus silicon-iron) and two patent-pending proprietary core designs: the C-I Core and the A-Core (angle-cut), which reportedly reduces excitation current by up to 50% relative to straight cut cores. Its customer base is concentrated in aerospace and defense (with stated 70+ year U.S. military and 50+ year NASA relationships), medical electronics, telecommunications, industrial controls, wiring devices (notably the largest-in-industry GFCI sensor core franchise), and electric vehicles, supported by ITAR registration, ISO 9001:2015, and AS9100:2016 Rev D certifications at the Anaheim, CA manufacturing facility.

The company has been a wholly owned subsidiary of Inductotherm Industries, a diversified industrial conglomerate, since 1977, and operates a multi-country manufacturing footprint including U.S. sites in Cherry Hill and Anaheim, lamination operations in Brantford, Ontario (Canada, since 1964), and Mexican facilities in San Juan del Rio (Metales Magneticos) and Nogales, Sonora (GFCI assembly). Historical growth has been driven by tuck-in acquisitions of adjacent specialists — Haddon Tool (1979, precision rotating components), SGL Industries (1985, tape wound toroidal cores), and National Arnold Magnetics (2003, the premier tape wound core manufacturer).

Revenue is generated through two streams: direct hardware sales of magnetic components (quote-based, sold via Regional Sales Representatives under a 25-50% travel enterprise field-sales model) and contract manufacturing services (toroidal core winding, bobbin winding, electro-mechanical assembly, final product packaging and distribution). The GTM motion is direct enterprise sales with technical support, design review, and testing provided from initial concept through production. The company does not publicly disclose pricing, revenue, or financial metrics; no public listing, no venture funding history, and no recent leadership changes are recorded in the input data.

Core offering

Magnetic Metals Corporation manufactures tape wound toroidal cores, tape wound cut cores, and related soft magnetic components used as the building blocks of transformers, inductors, chokes, and GFCI sensors. The company also provides contract manufacturing services including toroidal core winding, bobbin winding, and electro-mechanical assembly for ground fault circuit interrupters, arc fault detectors, transformers, and custom magnetic components, with final product assembly, packaging, and distribution.

Product overview

Magnetic Metals offers a comprehensive portfolio of magnetic components centered on tape wound toroidal cores and tape wound cut cores. The core product line includes Tape Wound Toroidal Cores providing near-perfect magnetic circuits for power transformers, inductors, and converters, and Tape Wound Cut Cores for custom transformer shapes with critical weight/dimensional requirements. Supporting products include the patented A-Core (cut-angle design reducing excitation current and noise) and the low-cost C-I Core combining cut cores with laminated I-bars. Amorphous Cores using metallic glass materials are offered for high-frequency, low-loss applications. Advanced-Grade Materials encompass a full spectrum of soft magnetic alloys including Supermalloy, Supermendur, SuperPerm variants, Square loop materials, and nanocrystalline alloys. Custom Services include contract manufacturing with toroidal core winding, bobbin winding, electro-mechanical assembly, and final product packaging/distribution. GFCI Cores & Assemblies serve wiring devices and electric vehicle charging applications.
