--- Why Choose Neodymium Magnets? ---
• Superior Strength and Performance:
Neodymium magnets are renowned for their exceptional magnetic strength, making them the preferred choice in high-performance applications. IT-MAG’s sintered NdFeB magnets achieve intrinsic coercive forces ranging from 12 to 40 KOe, thanks to advanced Grain Boundary Diffusion (GBD) technology. This allows for higher grades like N55H and N52UH—magnets that maintain stability even under extreme temperatures up to 200°C. For example, in electric vehicle (EV) motor applications, where efficiency and thermal resistance are critical, IT-MAG’s magnets outperform standard alternatives by reducing energy loss and enhancing torque density. In one real-world case, a Tier-1 EV motor manufacturer in Germany reported a 12% increase in motor efficiency after switching to IT-MAG’s GBD-treated N52H magnets, directly contributing to longer battery life and improved vehicle range. These magnets also exhibit superior remanence and energy product (BHmax), ensuring maximum performance in compact designs. Whether used in high-speed spindles or precision actuators, IT-MAG’s neodymium magnets consistently deliver unmatched power-to-size ratios. Their ability to sustain magnetization under mechanical stress and harsh environments makes them ideal for aerospace, robotics, and industrial automation. With over 17 years of R&D investment and a fully integrated production line—from raw material processing to final magnetization—IT-MAG ensures every magnet meets the highest standards of consistency and durability. This level of engineering excellence is why global leaders trust IT-MAG to power their most demanding technologies.

Thanks to IT-MAG’s Ni-Cu-Ni-Au multi-layer coating and Parylene surface treatment, the components passed rigorous biocompatibility and corrosion resistance tests, ensuring long-term reliability. In the automotive sector, IT-MAG has supplied magnets for brake-Hall sensors used in Ferrari’s high-performance models, where precision and durability under extreme heat and vibration are non-negotiable. Similarly, IT-MAG’s magnets are integral to throttle-Hall sensors in FIAT vehicles, enabling accurate fuel injection control. Beyond these, IT-MAG’s products are widely used in industrial tools, construction machinery, and consumer electronics. For instance, a major Chinese power tool manufacturer adopted IT-MAG’s high-torque NdFeB magnets in cordless drills, resulting in a 20% improvement in startup torque and reduced motor wear. These real-world applications underscore IT-MAG’s ability to tailor magnetic solutions to specific technical challenges—proving that whether it’s in a hospital operating room or on a construction site, IT-MAG delivers strong magnets for strong products.
--- IT-MAG's Manufacturing Process ---
• From Raw Materials to Final Products:
IT-MAG’s manufacturing process is a meticulously engineered journey from raw materials to finished magnetic components, all governed by the principle: 'Strong magnets for strong products.' The process begins with high-purity neodymium, iron, and boron sourced through the ZOEHIGH Group’s vertically integrated supply chain, ensuring consistent composition. These materials undergo strip casting to form thin ribbons, which are then hydrogen decrepitated into fine powder—a key step that enhances particle uniformity. The powder is jet-milled to submicron size and mixed with additives before being pressed in a magnetic field forming press, aligning the particles for optimal magnetic orientation. After pressing, the green compacts undergo germ inspection and are sintered in vacuum furnaces at temperatures between 1000–1100°C, transforming them into dense, crystalline structures. Subsequent machining, surface treatment, and final inspection ensure dimensional precision and surface integrity. Each batch is subjected to full characterization—including magnetic force testing, X-ray fluorescence analysis, and salt spray resistance checks—before magnetization. This end-to-end control, supported by automated systems and real-time monitoring, enables IT-MAG to produce over 3,000 tons annually with less than 0.5% defect rate. The entire process is conducted within a 20,000㎡ facility equipped with state-of-the-art equipment such as continuous sintering furnaces, isotatic presses, and weak magnetic magnetizing machines. Every stage is documented and traceable, reinforcing IT-MAG’s reputation for reliability and quality. This systematic approach not only ensures product consistency but also allows rapid scaling to meet growing demand across global markets.
• Commitment to Quality Control:
Quality is embedded into every layer of IT-MAG’s operations, starting with the lab and extending through production and delivery. The company operates a certified laboratory (Lab Mark: Lab, Related Number: 03-280) equipped with cutting-edge instruments including high-frequency infrared carbon and sulfur analyzers, inductively coupled plasma spectrometers, and X-ray fluorescence spectrometers—all essential for verifying elemental purity and homogeneity. Magnetic force testing is performed on every batch using Hall probes and fluxmeters to confirm Br, Hc, and BHmax values match specifications. Environmental stress tests are equally rigorous: salt spray tests (SST ≥24 hrs), constant temperature/humidity cycling, and high-low temperature impact tests simulate real-world conditions. For example, IT-MAG’s Ni-Cu-Ni-Ag coated magnets have demonstrated over 96 hours of protection in PCT (pressure cooker test), proving their suitability for outdoor and marine applications. The company also conducts accelerated aging tests at 120°C and 150°C to evaluate long-term stability—critical for use in EV motors and industrial drives. All results are logged and stored digitally for audit compliance. IT-MAG’s adherence to ISO9001, ISO14001, and TS16949 standards ensures that quality is not just a goal, but a measurable, repeatable process. Furthermore, the company holds Intellectual Property Management System Certification, reflecting its deep investment in innovation and process optimization. With 130 employees trained in lean manufacturing and Six Sigma principles, IT-MAG maintains a culture of continuous improvement. This unwavering focus on quality has enabled IT-MAG to secure long-term partnerships with global brands and earn recognition in sectors where failure is not an option.
