Our N52 neodymium magnets achieve a maximum magnetic energy product of 52 MGOe (416 kJ/m³), enabling our clients to downsize their designs without sacrificing performance. This high energy density makes N52 neodymium magnets ideal for compact high-efficiency motors, where smaller magnet sizes reduce overall product weight and manufacturing costs.
Products
n52 neodymium magnets
Our N52 neodymium magnets are the highest-performance standard-grade neodymium magnets available, engineered to deliver an industry-leading magnetic energy product of up to 52 MGOe – a 20% increase in magnetic strength compared to standard N42 grades. As a fully integrated manufacturer with 30 years of expertise, we produce N52 neodymium magnets from virgin neodymium-iron-boron alloy (≥95% purity, no recycled materials) using a proprietary sintering process that enhances grain structure and magnetic uniformity. This strict production control ensures every N52 neodymium magnet delivers consistent flux density, minimal coercivity loss, and exceptional dimensional accuracy, making it the go-to choice for applications where space is limited and magnetic strength is critical, such as drone motors, medical imaging equipment, and high-efficiency industrial pumps

Product Description
N52 Neodymium Magnets: Ultra-High Strength for Precision Industrial Applications
Core Advantages of Our N52 Neodymium Magnets
Industry-Highest Magnetic Energy Product
Proprietary Alloy Formula for Stability
Unlike generic N52 neodymium magnets that use low-cost holmium iron, we enhance our N52 magnets with high-grade dysprosium iron alloy, improving high-temperature stability and reducing flux loss. Our N52 neodymium magnets maintain 90% of their magnetic strength at 80°C, with SH-grade variants (N52SH) capable of withstanding temperatures up to 150°C for industrial applications.
Micron-Level Dimensional Precision
Our CNC grinding and slicing centers produce N52 neodymium magnets with dimensional tolerances as tight as ±0.01mm, even for ultra-thin or large-format components. Every N52 magnet undergoes optical comparator inspection to ensure perfect fit in precision assemblies, reducing waste and assembly time for our global clients.
Technical Specifications of N52 Neodymium Magnets
The table below outlines the standard parameters for our N52 neodymium magnets, including both standard and high-temperature variants. Custom sizes, coatings, and magnetization directions are available to meet your specific application requirements, including high-corrosion or high-stress environments.

Quality Control & Global Compliance for N52 Magnets
Every batch of N52 neodymium magnets undergoes a rigorous 16-step quality inspection process to ensure compliance with international standards. Our quality lab uses X-ray fluorescence spectrometers to verify raw material purity, digital gauss meters to test magnetic performance, and coordinate measuring machines (CMM) to validate dimensional accuracy. We maintain full traceability for every N52 neodymium magnet, from raw material lot numbers to final shipping documentation, ensuring complete accountability for clients in Europe, North America, and Asia. Our N52 magnets comply with IATF 16949 (automotive), ISO 9001, REACH, RoHS 2.0, and California Prop 65, enabling seamless global export.
IATF 16949:2016 ISO 9001:2015 REACH Compliant RoHS 2.0 Certified SGS 300+ Tests Passed
Packaging & Delivery for N52 Neodymium Magnets
Due to their high magnetic strength, our N52 neodymium magnets require specialized packaging to prevent magnetic interference, chipping, and demagnetization during transit. Each N52 magnet is individually wrapped in anti-static, magnetic-shielding film and placed in custom foam inserts within 8-cell reinforced plastic trays, then packed into export-grade corrugated cartons with additional magnetic shielding layers. We offer flexible delivery options: free sample shipments (5-10 standard N52 neodymium magnets) with 3-5 day express delivery, small-batch production (1-2 weeks lead time), and mass production (2-4 weeks lead time) with payment terms including T/T, L/C, and PayPal to suit your business needs.
