Product Descriptions
Sintered neodymium iron boron magnets-particularly N52 grade round discs-represent the most powerful magnetic materials available today. These high-energy magnets are manufactured in numerous diameters, thicknesses, and configurations to accommodate a wide range of technical and commercial needs.
You will find NdFeB magnets built into advanced equipment such as high-torque motors, BLDC drives, magnetic filtration systems, MRI scanners, precision sensors, audio components, and many other high-performance assemblies.
Our N52 neodymium round magnets deliver exceptional holding force thanks to their premium NdFeB composition. They are suitable for both industrial and consumer applications requiring compact yet extremely strong permanent magnets. Multiple coatings are available to enhance corrosion protection and extend service life in challenging environments. All materials comply with RoHS and CE requirements, ensuring safe entry into European markets.
Magnet Plating
We provide a variety of surface treatments designed to enhance durability and environmental resistance. Coating options include Ni-Cu-Ni, zinc, epoxy, gold, chrome, and customized finishes to match specific performance demands.
Complex & Custom Directions
While we categorize common directions (Axial, Diametral, Radial), the true number is limitless. The direction is a fundamental design choice, determined by the intended function of the magnet within the final assembly.
Application Fields
N52 round magnets are widely used wherever compact, ultra-strong permanent magnets are required. Their outstanding performance allows designers to reduce the size and weight of mechanical components across many industries.
Typical uses include:
High-strength holding fixtures • Precision sensors • Reed switches • Hard disk assemblies • Audio transducers • Headphones • Loudspeakers • MRI systems • Magnetic-drive pumps • Motors & generators • Tool holders • Magnetic bearings • Door latches • Dental and medical instruments • Magnetic separation systems • Lifting equipment • Arts & crafts • Model building • Wall displays • POP signage • Packaging closures • Jewelry mechanisms • Laboratory devices • Educational kits • and more.

FAQ
Q: Why choose N52 grade instead of lower grades like N35 or N42?
A: N52 offers the highest magnetic energy product available in mass production, providing significantly stronger pull force. It's ideal for applications where maximum strength is required in small dimensions.
Q: What coating is best for N52 round magnets?
A: Nickel (Ni-Cu-Ni) is the most durable and commonly used coating. For high-humidity environments, epoxy coating provides better corrosion resistance.
Q: Can N52 magnets be used in high-temperature applications?
A: Standard N52 magnets operate up to 80°C. If you require higher temperature tolerance, we can provide heat-resistant grades such as N42SH or N35EH.
Q: Do N52 neodymium round magnets break easily?
A: Neodymium magnets are strong but brittle. They should be handled carefully to avoid impact or snapping together. We can provide separators or fixtures for safer assembly.
Q: Can these magnets be customized for motors or sensors?
A: Yes. We support custom magnetization (axial, diametrical, multi-pole), tight tolerances, and special coatings required for motor or sensor applications.
