N48SH High-Performance Neodymium Iron Boron Permanent
Magnet – Superior Magnetic Strength for Advanced Engineering Applications This premium-grade N48SH neodymium iron boron (NdFeB) magnet delivers exceptional magnetic performance, combining high remanence and robust coercivity to meet the demands of modern industrial and technological systems. Engineered for applications requiring reliable and powerful magnetic fields, this material stands out in environments where efficiency, durability, and precision are non-negotiable. As a leading innovator in permanent magnet technology, our company specializes in developing and manufacturing advanced rare earth magnets tailored to diverse engineering needs—supporting product development from concept to production. Key Features: - Exceptional magnetic flux density (remanence) exceeding standard grades - Enhanced resistance to demagnetization (coercivity), ideal for high-temperature or dynamic conditions - Available with multiple surface treatments including nickel plating, zinc coating, black nickel finish, black epoxy resin, and phosphating for corrosion protection - Customizable shapes, sizes, and tolerances to fit specific design requirements - Consistent quality across batches, ensuring repeatability in mass production Detailed Description: The N48SH grade represents one of the highest-performing sintered NdFeB materials available today, offering an optimal balance between magnetic strength and thermal stability. Unlike conventional ferrite or alnico magnets, this rare earth alloy provides significantly higher energy product (BHmax), enabling smaller, lighter, and more efficient motor and generator designs. The material’s microstructure is optimized through precise heat treatment and grain alignment techniques, resulting in enhanced mechanical integrity and reduced sensitivity to environmental stressors such as moisture or vibration. Surface coatings not only improve corrosion resistance but also enhance compatibility with various assembly processes—whether for automated handling, bonding, or integration into complex assemblies. Applications: Ideal for use in electric machinery such as brushless DC motors, servo drives, and linear actuators; new energy sectors like wind turbines, hybrid vehicle motors, and electric powertrains; and machine building industries including CNC equipment, robotics, and precision automation tools. Whether you're designing next-generation EV components, high-efficiency HVAC systems, or cutting-edge medical imaging devices, N48SH offers the magnetic foundation needed for superior performance under demanding operational conditions. User Feedback: Engineers and product developers worldwide have praised this material for its consistent output in prototype testing and production runs. One client noted, “We were able to reduce motor size by 30% while maintaining torque output—thanks to the exceptional magnetic properties of N48SH.” Another user highlighted how the black epoxy finish improved long-term reliability in humid environments without compromising magnetic efficiency. Frequently Asked Questions: What makes N48SH different from other NdFeB grades? It offers a higher coercivity than standard N48 grades, making it suitable for applications involving elevated temperatures or strong opposing magnetic fields. Is this magnet suitable for outdoor or harsh environments? Yes—with proper surface treatment like black epoxy or phosphating—it can withstand exposure to salt spray, humidity, and temperature fluctuations. Can I request custom dimensions or special coatings? Absolutely. Our R&D team supports OEM customization for shape, tolerance, and finish based on your project specifications. How do I ensure compatibility with my existing design? Our technical support team provides assistance with magnetic modeling, finite element analysis (FEA), and prototyping to validate integration before full-scale production.
