High-Performance N52 Magnets: Extreme Power & Stability. Engineered with Hcj >=11kOe, these magnets provide the perfect balance of maximum pull force and enhanced resistance to demagnetization. Protected by a premium Ni-Cu-Ni triple coating, they ensure long-term reliability for industrial motors, sensors, and precision engineering.
High-Efficiency Motors: Optimized for BLDC motors and generators, offering high heat stability and demagnetization resistance (H>=11 kOe).
Precision Sensors: Reliable performance in Hall effect sensors and robotics requiring consistent magnetic flux and accuracy.
Industrial Filtration: Powerful magnetic separators for removing ferrous contaminants in food, chemical, and mining industries.
Advanced Electronics: Compact, high-power solutions for premium acoustics (speakers/headphones) and magnetic mounting systems.
Green Energy: Essential components for wind turbines and magnetic levitation (Maglev) technology research.
An N52 magnet is the highest grade of Neodymium (NdFeB) magnet currently available for commercial use. The “52” refers to its Maximum Energy Product (BH)max of 52 MGOe, meaning it provides approximately 20% more magnetic pull than the standard N35 grade of the same size.
Whether you are looking for super strong rare earth magnets for industrial applications, scientific research, or heavy-duty DIY projects, our N52 collection delivers unparalleled performance in a compact form factor.
Maximum Pull Force: Our N52 grade magnets are sintered to perfection, ensuring the strongest possible magnetic field.
Superior Coating (Ni+Cu+Ni): Each magnet is protected by a premium Nickel-Copper-Nickel triple layer to prevent corrosion and provide a smooth, rust-resistant finish.
Precision Engineering: We offer a standard tolerance of $\pm 0.05$ mm, making them ideal for high-precision engineering and assembly.
Versatile Shapes: Available in discs, blocks, rings, and countersunk styles to fit any project requirement.
Our customers use N52 magnets for a wide range of high-performance applications:
High-Efficiency Motors & Generators: Ideal for BLDC motors and wind turbines, where they must resist demagnetization from heat and reverse magnetic fields.
Precision Sensors & Actuators: Perfect for Hall effect sensors, magnetic switches, and robotics that require consistent magnetic flux and high-precision positioning.
Industrial Magnetic Separators: Used in heavy-duty filtration systems to remove fine ferrous contaminants in food, chemical, or mining processing lines.
Consumer Electronics & Acoustics: High-performance magnets for premium headphones, high-fidelity speakers, and magnetic closures in high-end mobile devices or wearables.
Clean Energy & Maglev Tech: Supporting magnetic levitation (Maglev) projects and experimental energy research that demand the highest power-to-weight ratio available.
N52 magnets are NOT toys. Due to their extreme strength:
Pinch Hazard: Keep fingers away from the attracting surfaces. They can snap together with enough force to cause injury.
Keep Away from Electronics: Ensure a safe distance from pacemakers, credit cards, and hard drives.
Fragility: Neodymium is a brittle material. Do not let magnets “slam” together, as they may shatter. Pro Tip: Slide magnets apart rather than pulling them.
Q: Can I get N55 or N60 magnets? A: Currently, N55 magnet is the highest reliable commercial grade. While higher numbers exist in lab settings, N52 offers the best stability and power-to-cost ratio for consumers.
Q: Will N52 magnets lose their strength over time? A: No, if under normal conditions (below 40°C), they lose less than 1% of their flux density over 10 years.
Q: Do you offer wholesale or custom sizes? A: Yes! We specialize in bulk N52 magnets and custom manufacturing. Contact our support for a quote.
