Six raw material families
Sintered Ferrite Powder
Anisotropic strontium ferrite powder for dry and wet pressing, including LaCo-substituted high-performance series for motor tiles and radial rings.
Bonded Permanent Ferrite Powder
Ferrite powders optimised for bonded magnets — rubber magnets, plastic magnets and calendered or extruded magnetic sheets.
Injection Molding Compound · Ferrite
Sr ferrite magnetic powder compounded with PA6, PA12 or PPS into ready-to-mold granules. 15 anisotropic grades with full magnetic, mechanical and molding data.
Injection Molding Compound · Rare Earth
Eight isotropic and anisotropic NdFeB / SmFeN / hybrid compound series in PA12 and PPS, covering Br from 250 to 910 mT.
Magnetic Recording Powder
Magnetic powders for bank card stripes, railway tickets, magnetic inks and recording media.
EM Wave Absorbing Materials
Flexible rubber absorbers and magnetic fillers for EMC and shielding in the 1–40 GHz range.
Components, to your drawing
Sintered or bonded, ferrite or NdFeB, rubber or plastic — Ruiyi manufactures the finished magnet as well as the powder behind it. Multipole rings, motor tiles, encoder targets and custom assemblies.
