Neodymium Iron Boron N55M Permanent
Magnet: High-Performance Rare Earth Magnetic Material for Advanced Engineering Applications This high-grade neodymium iron boron (NdFeB) magnet, specifically the N55M grade, represents a cutting-edge advancement in permanent magnet technology. As part of the third-generation rare earth magnet family, it delivers exceptional magnetic properties including high remanence, strong coercivity, and an impressive maximum energy product—making it one of the most powerful permanent magnets commercially available today. Designed for precision engineering needs, this material excels in environments where performance, reliability, and compact size are critical. Key Features: - Exceptional magnetic strength with a Br (remanence) value typically exceeding 1.4 Tesla - Enhanced resistance to demagnetization due to its high coercive force - Customizable surface treatments such as nickel plating, zinc coating, black epoxy, or phosphating for corrosion protection and aesthetic customization - Available in raw black sheet form without coating—ideal for applications requiring minimal surface interference - Engineered for consistent performance across wide temperature ranges, suitable for both industrial and consumer electronics Detailed Description: The N55M variant of neodymium iron boron is manufactured using advanced sintering techniques that optimize crystal alignment and microstructure uniformity. This results in superior magnetic flux density and mechanical integrity compared to older generations of ferrite or alnico magnets. Unlike standard NdFeB grades, the "M" suffix indicates a specific processing condition—often associated with medium-temperature stability or improved thermal resilience, which makes it particularly valuable in motor assemblies, sensors, and actuators operating under moderate heat exposure. The absence of any protective layer in the base form allows for direct integration into bonded magnet systems or further finishing during post-processing stages. With tailored manufacturing capabilities, our team supports custom shapes, tolerances, and magnetization patterns to meet unique project specifications. Ideal Use Cases: This magnet is widely used in electric vehicle drivetrains, wind turbine generators, robotics, medical imaging devices like MRI machines, high-efficiency motors, and aerospace components. It’s also a preferred choice for engineers developing compact speakers, vibration motors, magnetic couplings, and smart home automation systems where space constraints demand maximum magnetic output per volume. Its compatibility with various coating technologies ensures durability in humid, salty, or chemically aggressive environments—making it suitable for marine, automotive, and outdoor industrial settings. Customer Feedback: Users consistently highlight the magnet's ability to enhance device efficiency while reducing overall weight and size. Engineers report improved torque-to-weight ratios in brushless DC motors and better signal consistency in sensor applications. Many appreciate the flexibility in surface finish options and the rapid turnaround time for sample orders, which accelerates prototyping cycles and reduces development costs. Frequently Asked Questions: What does the “N55M” designation mean? It refers to the intrinsic magnetic performance level (N55) combined with a modifier (M), often indicating a particular thermal stability class or manufacturing process optimization for enhanced reliability at elevated temperatures. Is this magnet suitable for outdoor use? Yes, when paired with appropriate coatings such as black epoxy or nickel plating, it offers excellent resistance to oxidation and environmental degradation, making it ideal for long-term outdoor deployment. How do I handle these magnets safely? Due to their intense magnetic fields, proper handling tools and safety precautions are recommended—especially around electronic devices, pacemakers, and ferromagnetic materials. Why choose N55M over other NdFeB grades? It provides a balanced combination of high magnetic output and thermal stability, offering more predictable performance than higher-grade variants (like N58 or N60) in applications involving intermittent heating or variable load conditions. For designers seeking robust, scalable solutions powered by next-gen rare earth magnets, the N55M neodymium iron boron material stands out as a versatile and future-ready component—enabling innovation across industries from renewable energy to precision robotics.
