Magnet for Advanced Engineering Applications Discover the N55 grade sintered neodymium iron boron (NdFeB) magnet, a premium-grade permanent magnet material engineered for superior magnetic flux density, thermal stability, and long-term reliability. Designed for demanding industrial environments, this high-performance rare earth magnet delivers exceptional energy product values, making it ideal for precision applications across multiple sectors including electric mobility, medical imaging, and advanced motor systems. Key Features: - Exceptional magnetic strength with maximum energy product (BH)max exceeding 55 MGOe - Nickel-copper-nickel multi-layer coating for corrosion resistance and durability - Customizable magnetization patterns (multi-level, axial, radial, or complex configurations) - Precision-sintered manufacturing process ensuring dimensional accuracy and consistent performance - Available in various shapes and sizes for OEM integration and design flexibility Detailed Description: The N55 series represents one of the highest commercially available grades in the sintered NdFeB family, offering an optimal balance between coercivity and remanence. This grade is particularly suited for applications requiring strong magnetic fields in compact form factors—such as brushless DC motors, voice coil actuators, and magnetic resonance imaging (MRI) systems. The nickel-based plating provides enhanced protection against oxidation, while the sintered microstructure ensures mechanical integrity under dynamic load conditions. Our proprietary manufacturing techniques enable tight tolerances and repeatable performance, critical for high-volume production lines and mission-critical devices. Whether you're developing next-generation electric vehicle drivetrains or compact servo motors, this magnet supports innovation through its robust physical and magnetic properties. Applications: This high-strength neodymium magnet is widely adopted in new energy vehicles (NEVs), where it powers traction motors, power steering systems, and regenerative braking components. Beyond automotive, it serves in industrial automation equipment, wind turbines, robotics, aerospace actuators, and consumer electronics such as hard disk drives and smartphone vibration motors. Its use in nuclear magnetic resonance machines underscores its ability to maintain stable field alignment even under extreme environmental conditions. For engineers seeking reliable, high-efficiency solutions, the N55 grade offers a compelling alternative to older ferrite or alnico materials. User Feedback: Engineers from global R&D teams have praised the magnet’s consistency in performance across temperature ranges (-40°C to +150°C). One client noted that the customizable magnetization options significantly improved torque density in their EV motor design, reducing overall system weight by up to 12%. Another user highlighted the rapid sample turnaround and responsive technical support during prototyping phases—an advantage when time-to-market is crucial. Frequently Asked Questions: What makes the N55 grade different from other
Ndfeb Magnets? The N55 designation indicates a specific level of magnetic energy product; higher grades like N55 offer greater flux output than lower ones (e.g., N42), but may require more careful handling due to increased brittleness. It strikes a practical balance between performance and manufacturability for most industrial uses. Is the nickel coating sufficient for outdoor or humid environments? Yes, the triple-layer Ni-Cu-Ni finish provides excellent resistance to moisture and chemical exposure, making it suitable for both indoor and outdoor applications—even in coastal or high-humidity regions. Can I request custom magnetization directions? Absolutely. We offer tailored magnetization profiles including single-pole, multi-pole, and segmented configurations to match your device’s electromagnetic requirements. How quickly can I receive samples or bulk orders? We provide fast-turnaround sample kits within 3–5 business days and efficient mass production scheduling for large-scale deployments, supported by our dedicated assembly R&D team and quality assurance protocols.
