Magnosphere

What Magnosphere does

Magnosphere GmbH is a German-headquartered specialty magnet manufacturer founded in 2011 in Troisdorf, operating a vertically integrated 'mine-to-magnet' supply chain that includes direct rare-earth sourcing in China and manufacturing in Hangzhou. The company produces permanent magnets (NdFeB, SmCo, AlNiCo, ferrite/ceramic), flexible magnetic sheets and strips, magnetic assemblies (including Halbach arrays and magnetron sputtering targets), soft magnetic materials, electromagnets, bonded magnets, rotor and stator components, and metal injection-molded parts. It also sells in-house magnetizing systems as a product line, indicating ownership of the full production equipment stack. The business maintains a Class 1000 cleanroom and parylene coating capability, supporting high-spec assembly work.

The company serves aerospace and defense, medical devices, automotive, oil and gas, industrial automation, advertising/commercial printing, and academic/R&D customers, with named certifications including AS9100 Rev D, ISO/TS 16949, ITAR compliance, ISO 9001:2015, and ISO 14001. Revenue is generated through a hybrid go-to-market: B2B quote-based contracts for custom-engineered magnetic assemblies and OEM supply for high-spec verticals, plus a public e-commerce storefront for catalog magnets and flexible magnetic products. Operational footprint extends across Troisdorf, Cologne, and Siegburg in Germany, San Diego, San Jose, and Kentucky in the United States, and Hangzhou in China. Differentiated technical assets include the proprietary SmCo 35E high-power-density samarium-cobalt magnet, HTSC YBCO superconducting development, and a publicly disclosed partnership with Starship Technologies for autonomous delivery robots.
