Features
Ultra-High Magnetic Performance:
Industry-Leading BHmax: Delivers 20% higher energy density than N42 magnets, enabling 30% smaller motor designs without sacrificing torque (e.g., 10mm disc holds 65N pull force).
Low Field Decay: Maintains ≥95% remanence after 10 years of static use, outperforming alnico and ferrite magnets in long-term stability.
Precision and Durability:
Tight Tolerances: Machined to ISO 2768-mk standards (±0.02mm for diameters ≤10mm), ensuring seamless integration into high-precision devices like MRI probes and aerospace sensors.
Triple-Layer Protection: 25μm Ni-Cu-Ni plating passes 1000-hour salt spray tests (ASTM B117), suitable for marine robotics and outdoor industrial equipment.
Application Flexibility:
Multi-Pole Magnetization: Supports up to 16 poles per inch for axial magnetization, critical for reducing cogging in high-speed drone motors (rpm >10,000).
Temperature Management: While rated for 80°C, optional ceramic coating extends max temp to 120°C (contact us for high-temp variants).
Application
Aerospace Components: Used in fly-by-wire systems and inertial navigation sensors, where compact, strong magnets are non-negotiable for weight-sensitive aircraft.
Medical Devices: Integrates into miniaturized insulin pumps and hearing aids, providing reliable magnetic coupling without interference with MRI compatibility (when shielded).
High-Power Motors: Powers e-bike motors and robotic arms, achieving 20% higher power density than lower-grade magnets, enabling faster acceleration and longer battery life.
Magnetic Levitation (Maglev): Critical for levitation systems in high-speed trains, where precise magnetic fields maintain 1-2mm air gaps at 500 km/h.
FAQ
Q: Why is N52 more expensive than lower grades?
A: N52 requires higher-purity raw materials (99.9% Nd) and tighter manufacturing controls, resulting in a 30% higher production cost compared to N42.
Q: Can N52 magnets be re-magnetized after demagnetization?
A: No, sintered NdFeB is a permanent magnet; re-magnetization requires industrial-grade electromagnets and is not feasible for field repairs.
Q: What is the recommended air gap for maximum pull force?
A: For a 10mm disc, maximum pull force (65N) is achieved at <1mm air gap with a mild steel armature (≥1mm thickness).
Q: Do you offer uncoated N52 magnets for bonding applications?
A: Yes, raw N52 magnets (uncoated) are available for adhesive bonding, with a surface roughness Ra ≤1.6μm for optimal glue adhesion.
