N42
Neodymium Iron Boron Magnet – High-Performance Rare Earth Permanent
Magnet for Advanced Applications This N42 grade neodymium iron boron (NdFeB) magnet is engineered for superior magnetic performance, offering a minimum energy product of 42 MGOe, making it ideal for high-efficiency applications across industries such as consumer electronics, industrial motors, medical devices, and precision sensors. As one of the strongest permanent magnet materials available today, this rare earth magnet delivers exceptional strength-to-size ratio, enabling compact, powerful designs in modern engineering projects. Whether you're developing advanced robotics, electric vehicles, or high-fidelity audio systems, this magnet provides reliable magnetic flux density and thermal stability under operational conditions. Key Features: - High coercivity ensures resistance to demagnetization - Excellent mechanical integrity for durable performance - Available in multiple surface finishes including nickel plating, zinc coating, black epoxy, phosphating, and black nickel for corrosion resistance and aesthetic customization - Consistent magnetic properties across batches for quality assurance - Customizable shapes, sizes, and tolerances for tailored integration into end products Detailed Description: The N42 neodymium magnet is manufactured using advanced sintering techniques that optimize crystal alignment, resulting in enhanced magnetic output without compromising structural durability. Its composition—primarily neodymium, iron, and boron—offers a balanced blend of cost-effectiveness and performance, outperforming traditional ferrite and alnico magnets in both strength and efficiency. The material’s ability to maintain stable operation at elevated temperatures (up to 80°C depending on grade) makes it suitable for demanding environments where consistent magnetic output is critical. Surface treatments like nickel-copper-nickel layers provide excellent protection against oxidation, while black epoxy coatings offer an attractive, non-conductive finish ideal for sensitive electronic components or decorative applications. Applications: Commonly used in high-performance motors, magnetic couplings, loudspeakers, hard disk drives, MRI machines, wind turbines, and industrial automation equipment. This specific grade is also widely adopted in large-scale educational toys and interactive learning kits due to its robustness, safety when properly encapsulated, and ability to deliver engaging tactile feedback through magnetic interaction. For designers seeking strong yet lightweight solutions, N42 offers a compelling alternative to heavier ferromagnetic materials.
