N48H
Neodymium Iron Boron Magnet: High-Performance Rare Earth Permanent
Magnet for Advanced Electronics and Industrial Applications Our N48H neodymium iron boron (NdFeB) magnet is a premium-grade permanent magnetic material engineered for superior performance in demanding environments. As a leading innovator in high-strength rare earth magnet technology, we specialize in developing custom solutions tailored to the unique needs of global engineering and manufacturing sectors. These magnets are ideal for applications where compact size, exceptional magnetic flux density, and thermal stability are critical—making them indispensable in modern consumer electronics, robotics, medical devices, and industrial automation systems. Key Features: - Exceptional magnetic strength with energy product up to 48 MGOe - Enhanced thermal resistance up to 120°C without significant flux loss - Multiple surface treatments including nickel plating, zinc coating, black epoxy, phosphating, and black nickel for corrosion protection and aesthetic customization - Precision-engineered dimensions and consistent magnetic alignment for reliable integration into complex assemblies - Customizable geometries and grades beyond standard N48H to meet specific project requirements Detailed Description: The N48H grade represents one of the most widely adopted neodymium iron boron materials due to its optimal balance between coercivity and remanence. Unlike conventional ferrite or alnico magnets, this rare earth alloy delivers significantly higher flux output in smaller volumes—a key advantage for miniaturized designs in smart devices and wearable tech. Our proprietary sintering process ensures uniform grain structure and minimal internal stress, resulting in improved mechanical integrity and long-term reliability. The available finishes—such as black epoxy for EMI shielding or phosphated coatings for enhanced adhesion in bonding processes—allow seamless integration across diverse industries. Whether you're designing a brushless DC motor, a magnetic sensor array, or a precision actuator, our magnets offer the magnetic consistency needed for high-volume production runs. Use Cases: This high-performance magnet finds extensive use in electric vehicles (EVs), wind turbines, hard disk drives, speakers, headphones, MRI components, and automated machinery. Its ability to maintain stable magnetic properties under continuous operation makes it suitable for both static and dynamic applications. Engineers working on compact motor designs benefit from its high Br (residual induction) while maintaining sufficient Hc (coercive force) to resist demagnetization under external fields. Additionally, its compatibility with various assembly methods—including adhesive bonding, press-fitting, and screw mounting—adds flexibility during product development. Customer Testimonials: “Used these N48H magnets in our new line of wireless earbuds—they provided the necessary hold and signal clarity without increasing device thickness.” “Custom shape and nickel finish made installation effortless in our drone motor assembly. Quality control was outstanding throughout the process.” “We needed a solution that could withstand elevated temperatures in our industrial gearbox. These magnets performed flawlessly even at 115°C.” Frequently Asked Questions: What sets N48H apart from other NdFeB grades? N48H offers an excellent combination of high remanence and moderate coercivity, making it ideal for applications requiring strong yet stable magnetic fields. It strikes a balance between cost-efficiency and performance, outperforming lower grades like N35 while being more affordable than ultra-high grades such as N52. Can I get samples before placing a bulk order? Yes, we provide free sample units for evaluation prior to full-scale procurement. This allows engineers to test magnetic behavior, dimensional accuracy, and surface compatibility in real-world conditions. How do different coatings affect performance? Each finish serves a functional purpose: nickel enhances corrosion resistance; black epoxy adds electromagnetic shielding and improves aesthetics; phosphating boosts adhesion for potting compounds; and black nickel provides a matte appearance with moderate environmental protection. Is this magnet suitable for outdoor or humid environments? With proper coating—especially black epoxy or zinc—the N48H magnet can perform reliably in humid or salty atmospheres. For extreme conditions, we recommend consulting our technical team for customized protective solutions.
