N48
Neodymium Iron Boron Magnet: High-Performance Rare Earth Permanent
Magnet for Precision Applications Discover the power of N48 neodymium iron boron (NdFeB) magnets—engineered for exceptional magnetic strength, durability, and reliability in demanding environments. These high-grade rare earth permanent magnets are crafted using advanced sintering technology to deliver superior energy product (BH)max and coercivity, making them ideal for industries that prioritize precision, efficiency, and long-term performance. Whether you're developing consumer electronics, industrial automation systems, or innovative packaging solutions, our N48 grade magnets provide a robust foundation for your next breakthrough. Key Features: - Exceptional magnetic flux density and resistance to demagnetization - Consistent performance across temperature ranges from -40°C to 150°C - Customizable shapes, sizes, and coatings for tailored integration - High mechanical strength with minimal weight—ideal for space-constrained designs - Environmentally compliant manufacturing process with low environmental impact In-depth Description: The N48 neodymium magnet is part of the second-generation rare earth permanent magnet family, offering a balance between magnetic output and cost-effectiveness. Unlike standard ferrite or alnico magnets, this material delivers up to 30% higher flux density, enabling more compact and efficient device designs. Its enhanced coercive force ensures stability even under extreme operating conditions, such as high vibration, thermal cycling, or exposure to external magnetic fields. With a maximum energy product of approximately 48 MGOe (Mega-Gauss Oersteds), it outperforms many alternatives while maintaining excellent dimensional accuracy and surface finish. Our proprietary coating technologies—including nickel-copper-nickel plating and epoxy encapsulation—protect against corrosion, extending service life in humid or chemically aggressive environments. Application Scenarios: These powerful magnets are widely used in modern engineering applications where precise positioning, secure fastening, or strong adhesion is critical. In retail packaging, they enable magnetic closures on luxury gift boxes, ensuring products remain securely sealed during shipping and display without damaging contents. For industrial equipment, N48 magnets support sensor alignment in motors, generators, and actuators, improving system efficiency and reducing maintenance needs. They also serve as key components in medical devices like MRI machines, wind turbine generators, and electric vehicle drivetrains—where consistent performance under load is non-negotiable. Additionally, hobbyists and prototyping engineers leverage these magnets for robotics, DIY projects, and educational tools due to their versatility and ease of integration. Customer Testimonials: “I was amazed by how much stronger the N48 magnets felt compared to other options I tested. The magnetic hold on my custom-designed product box was perfect—it stayed closed during transit but opened smoothly when needed.” – Sarah L., Product Designer, Europe “Used these in our new smart home device assembly line. The consistency in magnetic output across batches eliminated calibration issues we had with cheaper alternatives.” – Thomas R., R&D Engineer, North America Frequently Asked Questions: What makes N48 different from other neodymium grades? N48 offers one of the highest energy products among commercially available NdFeB materials, striking an optimal balance between raw magnetic strength and manufacturability. It’s particularly suited for applications requiring both high performance and reliable mass production. Are these magnets safe for use around sensitive electronics? Yes, provided proper shielding and distance are maintained. While the magnetic field is intense, controlled placement ensures no interference with electronic circuits or data storage devices. How do I prevent corrosion in humid climates? Our magnets come with durable protective coatings such as Ni-Cu-Ni or epoxy resin, which significantly enhance resistance to moisture and oxidation. For outdoor or marine-grade applications, consider specifying a thicker layer of protective treatment. Can I request custom magnet shapes or dimensions? Absolutely—we specialize in OEM and ODM services, allowing clients to specify custom geometries, tolerances, and magnetization directions based on specific project requirements. This flexibility supports innovation across sectors including aerospace, automotive, and consumer goods.
