Daido Steel Co., Ltd. is a Japanese specialty steel and advanced materials manufacturer headquartered in Nagoya, Aichi Prefecture. Founded in 1916, Daido Steel is listed on the Tokyo Stock Exchange (TYO: 5471) and operates several business divisions covering specialty steels, high-performance materials, magnetic materials, and forged components.

Through its specialized magnet subsidiary Daido Electronics Co., Ltd. (headquartered in Nakatsugawa, Gifu Prefecture) and dedicated research centers, Daido Steel develops heavy-rare-earth-free neodymium hot-deformed magnets, bonded rare earth magnets, and high-purity soft magnetic alloy powders that serve as key components in automotive electric drive systems.

Offer

Daido Steel and its subsidiary Daido Electronics provide permanent rare-earth magnets, bonded magnets, and soft magnetic powder metals:

  • Hot-Deformed Neodymium Magnets: Heavy-rare-earth-free anisotropic Nd-Fe-B magnets fabricated via proprietary hot plastic deformation processing, achieving high thermal stability and magnetic flux for hybrid and electric vehicle drive motors without relying on dysprosium (Dy) or terbium (Tb).
  • Polymer-Bonded Neodymium Magnets: Isotropic and anisotropic Nd-Fe-B bonded magnets, including thin-wall ring magnets for spindle motors, office automation (OA) devices, and automotive sensors.
  • Samarium-Iron-Nitrogen (SmFeN) Bonded Magnets: High-coercivity bonded magnetic rings and components offering strong corrosion and oxidation resistance.
  • Soft Magnetic Metal Powders: High-purity soft magnetic metal powders produced by proprietary gas atomization technology, widely used as core materials in automotive reactor coils and hybrid electric vehicle (HEV) boost converters to reduce volume by up to 30% and minimize core loss.
  • Electromagnetic Soft Steels & Strips: High-permeability soft magnetic alloys and cold-rolled strips optimized for electromagnetic actuators and sensor applications.
