Quadrant

What Quadrant does

Quadrant International Co. Ltd., headquartered in San Jose, California and operating since 1992, is a privately held global manufacturer of advanced magnetic technologies. Its core products include sintered NdFeB permanent magnets, soft magnetic materials (amorphous, nanocrystalline, Fe-Si, Fe-Ni, and Fe-Co alloys, ferrites, and soft magnetic composites), haptic motors (flat/pancake, linear resonant actuators, eccentric rotor, and acoustic), Metal Injection Molding (MIM) precision components, magnetizing systems, and motor systems including drone/UAV units. Distinctive process technology includes grain boundary diffusion (GBD) for high-coercivity N55H-grade magnets with efficient heavy rare earth utilization, programmable magnetization/magnet printing, and 3D magnetic field mapping using Brockhaus and Senis measurement systems.

The company serves Tier-1 and Tier-2 automotive customers, consumer electronics OEMs, industrial manufacturers (oil and gas, robotics, lifting, power tools, fluid handling), medical device makers, and aerospace customers. Manufacturing is concentrated at the Hangzhou Xiangxian Technology (杭州象限科技) and Changde facilities in China (130,000 sqm of installed solar, claimed 100% base-load energy efficiency) and at the 45,000 sq ft R&D, testing, and manufacturing site in Louisville, Kentucky, where the NeoGrass rare earth magnet manufacturing campus was announced in January 2022. The company also maintains local presence in Germany, Japan, Mexico, and Vietnam, and operates a subsidiary, Lab Magnetics Inc., in San Jose.

Revenue is generated through direct B2B enterprise sales of hardware (magnets, motors, magnetizing equipment), custom manufacturing services (MIM, prototyping, surface treatment), and engineering collaboration from design through mass production. Pricing is quote-based and not publicly disclosed. Demand generation relies on industry conferences (CWIEME, Magnetics Show, Electric & Hybrid Aerospace Technology Symposium, Coiltech), technical whitepapers, a published Magnetics Calculator mobile/web application, and a newsletter subscription funnel. No public financial disclosures, funding rounds, M&A, or leadership changes were identified in the available source material.
