Ultra-high-coercivity grades for automotive and industrial drives up to 180°C.
≤180°CEH Series
Extreme-temperature grades for the harshest operating conditions, 200°C and above.
≤200°C+By Shape (Geometry)
Block / Bar
Rectangular and square blocks, bars with or without holes. Common in linear actuators and holding assemblies.
Disc / Cylinder
Circular discs and cylinders for sensors, speakers and rotary assemblies with precise diameter and thickness.
Ring
Axially or diametrically magnetized rings for motors, encoders and coupling applications.
Arc / Segment
Curved segments and magnetic tiles (瓦形) for rotor and stator stacks in BLDC and traction motors.
Custom Shape
Drawings-based custom geometries, counterbores, chamfers and complex multi-pole magnet arrays.
Applications
Where Our NdFeB Magnets Perform
Motors & Generators
Permanent-magnet motors and generators rely on high-energy NdFeB for compact, efficient designs across industrial and appliance use.
Suggested grades: N / M / H (SH for higher temp)
EV Traction
Traction motors for electric vehicles demand high coercivity and thermal stability under continuous load and wide speed ranges.
Suggested grades: SH / UH / EH
Servo & BLDC
Servo and brushless DC motors require consistent flux, tight tolerances and reliable multi-pole magnetization for precision control.
Suggested grades: N / H / SH
Acoustic / Speakers
Speakers, headphones and micro-acoustic devices use small, high-strength magnets for clear, high-fidelity sound in compact form factors.
Suggested grades: N / M (Disc & Ring)
Wind Power
Direct-drive wind-turbine generators use large NdFeB assemblies where reliability and high-temp stability reduce maintenance.
Suggested grades: H / SH / UH
Consumer Electronics
Hard drives, sensors, vibration motors and smart-hardware actuators leverage miniature, high-performance magnets.
Suggested grades: N / M (Custom & Block)
Medical / Aerospace
High-reliability magnets for imaging, instruments and aerospace actuators where traceability and stability are critical.
Suggested grades: SH / UH / EH (with full certs)
