N52 Neodymium Disc Magnets
The Pinnacle of Magnetic Strength
Upgrade to the strongest commercial grade available. Our N52 Neodymium Disc Magnets provide approximately 20% more magnetic energy than standard N42 magnets, offering the highest pull-force-to-size ratio on the market. Engineered for precision and extreme holding power, these rare earth NdFeB discs are the primary choice for aerospace engineering, high-efficiency motors, and advanced industrial assemblies.
- Maximum Performance: Grade N52 represents the highest energy product (BHmax) currently manufactured.
- Triple-Layer Protection: Every disc features a premium Ni-Cu-Ni (Nickel) coating for superior corrosion resistance and durability.
- Precision Sizing: Available in diameters from micro-discs to heavy-duty industrial sizes to fit any project requirement.

Why Choose Grade N52 Over Other Neodymium Magnets?
While N35 or N42 magnets are sufficient for basic household tasks, N52 Grade magnets are required when space is limited but maximum performance is non-negotiable. With a BrMax of up to 14,800 Gauss, these magnets allow engineers to reduce the overall weight and footprint of their assemblies without sacrificing magnetic flux.
Technical Specifications & Applications
As a leader in magnet distribution for over 15 years, CMS Magnetics ensures that every N52 disc is ISO-certified and patent-licensed. Our N52 neodymium disc magnets are magnetized through the thickness (axially) and are widely used in:
- High-Torque Motors: Achieving greater efficiency in EV motors and generators.
- Sensors & Medical Devices: Providing reliable, high-sensitivity magnetic fields for precision equipment.
- Industrial Fabrication: Securely holding, lifting, and jigging heavy steel components.
- Innovative DIY & Prototyping: From magnetic levitation tracks to high-end cabinetry and retail displays.
Handling & Safety for High-Strength Magnets
Due to their extreme pull force, N52 magnets must be handled with care. These are not toys; they are industrial-strength tools that can cause injury if allowed to snap together. We recommend using spacers for storage and wearing gloves when handling larger discs.
CAUTION: Please read all safety instructions before handling these high-strength magnets.

FAQs
- How much stronger is N52 than N35? An N52 magnet is roughly 50% stronger in terms of magnetic energy product than an N35 magnet of the same size.
- What is the max temperature for N52 discs? Standard N52 magnets are rated for up to 80°C (176°F). If your project involves higher heat, please contact us for high-temperature (SH or UH) N52 options.
- Can I get N52 magnets with adhesive? Yes, we offer N52 discs with genuine 3M adhesive backing for easy application to non-magnetic surfaces like wood, plastic, or glass.
