From magnetic powder to finished components — engineered to spec.
Ruiyi develops and manufactures ferrite powders, injection-molding compounds and permanent magnet components for motors, sensors and precision assemblies. Full grade portfolio, dual-unit technical data, and custom compounding.
Two product lines, one supply chain.
Ruiyi supplies both the magnetic raw materials and the components made from them — so your specification stays consistent from powder to part.

Built for engineers, not just catalogs.
Complete grade coverage
From dry-pressed ferrite powder to SmFeN composites — one source across ferrite, NdFeB and rare-earth compound systems.
Custom compounding
Binder (PA6 / PA12 / PPS), filler loading and magnetic orientation can be tailored to your part and process window.
Transparent technical data
Magnetic, mechanical, physical and injection-molding parameters published in both SI and CGS units.
Powder-to-part integration
Materials and components under one roof, with fewer tolerances lost between suppliers.
