What Arnold Magnetic Technologies does

Arnold Magnetic Technologies is a Rochester, NY-headquartered manufacturer of high-performance permanent magnets, precision magnetic assemblies, electric motors, flexible magnetic composites, electromagnets, and ultra-thin precision metals, founded in 1895 and operating from 13 facilities across the United States, United Kingdom, Switzerland, Thailand, and China. The company serves more than 2,000 clients worldwide in aerospace and defense, motors and drives, medical devices, motorsports, oil and gas, energy generation, energy storage, consumer electronics, and advertising/commercial printing, with aerospace and defense and motors/industrial flagged as primary segments.

Its core technology centers on proprietary RECOMA samarium cobalt (SmCo) magnets, including the RECOMA 35E grade claimed as the world's most power-dense SmCo, neodymium iron boron (NdFeB) magnets in grades up to N55 and AH, L-Type laminated magnets with sub-20 μm insulation, Wraptite carbon fiber encapsulation for high-speed rotors, Arnokrome ductile magnetic alloys, Arnon non-grain-oriented silicon steel, and Precision Thin Metals rolled to 2 microns in titanium, nickel, aluminum, stainless steel, copper, Inconel, and specialty alloys. The company is ITAR registered, DFARS 225.7018 / NDAA 2019 compliant, AS9100 Rev D and ISO 9001:2015 certified, and Nadcap accredited for heat treatment. A Western rare earth supply chain anchored on Less Common Metals and Solvay plus a joint venture interest in the GQD rare earth mine in China supports the RECOMA mine-to-magnet positioning.

Revenue is generated primarily through direct enterprise B2B sales with quote-based pricing, supported by an engineering-led GTM in which the Middleton, WI Technology Center co-designs solutions with customer engineering teams. A smaller consumer e-commerce channel sells prefab Alnico, Ceramic, and Flexible magnets, magnetic viewers, and magnetizers. Arnold is a wholly owned subsidiary of Compass Diversified Holdings (NYSE: CODI), and operates divisions including Flexmag Industries, Ramco Electric Motors, and Ogallala Electronics.
