--- 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 across industries such as automotive, medical devices, industrial tools, and consumer electronics. At IT-MAG, we harness the full potential of NdFeB (Neodymium Iron Boron) technology to deliver magnets with superior magnetic force, high coercivity, and excellent thermal stability. Our advanced Grain Boundary Diffusion (GBD) technology allows us to produce high-grade magnets like N55H, which were previously unattainable using conventional methods. This breakthrough enables us to maintain strong magnetic induction while significantly enhancing resistance to demagnetization—critical for applications operating under extreme conditions. For example, in high-temperature environments such as electric vehicle motors or aerospace systems, our GBD-treated magnets retain up to 90% of their magnetic performance at 150°C, outperforming standard grades by a significant margin. Additionally, our rigorous quality control processes—including X-ray fluorescence spectrometry, high-frequency infrared carbon/sulfur analysis, salt spray testing, and temperature cycling—ensure every magnet meets international standards like ISO9001, ISO14001, and TS16949. With an annual output of 3,000 tons from our 20,000㎡ factory and a team of 130 skilled professionals, IT-MAG delivers consistent, reliable performance that drives innovation and efficiency in your products.

• Expertise and Experience in Magnet Manufacturing:
With over 17 years of industry experience and deep integration within the ZOEHIGH Group—a vertically integrated rare earth materials powerhouse—IT-MAG has built a robust foundation in raw material sourcing, R&D, and precision manufacturing. Our access to premium neodymium and heavy rare earth elements (Tb/Dy) ensures stable supply chains and cost advantages without compromising on quality. We’ve successfully partnered with global giants such as Ferrari and FIAT, delivering custom magnetic solutions for critical components like brake-Hall sensors and throttle-Hall sensors. These collaborations have not only validated our technical capabilities but also demonstrated our ability to meet stringent automotive safety and performance standards. Our production line follows a meticulously controlled 12-step process—from strip casting and hydrogen decrepitation to sintering, machining, surface treatment, and final magnetization—each stage reinforced by the mantra 'Strong magnets for strong products.' Every batch undergoes comprehensive lab testing, including magnetic force verification, humidity and corrosion resistance assessments, and mechanical durability checks. This level of diligence ensures that our magnets perform consistently in real-world applications, whether in harsh industrial environments or sensitive medical equipment. As a certified ISO9001 and CNAS-accredited facility, IT-MAG stands as a trusted partner for OEMs and system integrators worldwide seeking dependable, high-performance magnetic solutions.
• Commitment to Quality and Innovation:
At IT-MAG, innovation is not just a goal—it’s embedded in our DNA. We invest heavily in R&D to push the boundaries of what’s possible in permanent magnet technology. Our proprietary Grain Boundary Diffusion (GBD) process exemplifies this commitment: by precisely diffusing heavy rare earth elements (Dy/Tb) into the grain boundaries of sintered NdFeB magnets, we achieve a dramatic increase in intrinsic coercive force—up to 40 KOe—without sacrificing magnetic flux density. This means higher-grade magnets like N54H and N52UH can now be produced efficiently and reliably, enabling next-generation motor designs with improved efficiency and reduced size. Our lab, equipped with state-of-the-art instruments such as inductively coupled plasma spectrometers, XRF analyzers, and environmental chambers for high/low-temperature impact testing, ensures every product exceeds expectations. Furthermore, we offer a wide range of coatings tailored to specific application needs: from standard Ni-Cu-Ni for general use to Parylene and Teflon for extreme environments involving moisture, chemicals, or high temperatures. Real-world success stories include supplying magnets for high-precision Hall sensors used in Ferrari’s braking systems, where reliability under dynamic stress is non-negotiable. These partnerships underscore our dedication to excellence and continuous improvement. By combining cutting-edge technology, strict quality control, and customer-centric service, IT-MAG doesn’t just supply magnets—we empower your innovation.

• From Raw Material to Final Product:
Every IT-MAG neodymium magnet begins with precision engineering and ends with flawless performance. Our end-to-end production process starts with raw material blending, where we carefully mix neodymium, iron, and boron with trace heavy rare earth elements (Tb/Dy) to achieve target magnetic properties. The alloy is then subjected to strip casting—a rapid solidification technique that creates thin, uniform flakes ideal for subsequent processing. Next comes hydrogen decrepitation, where hydrogen gas breaks the alloy into fine particles, followed by jet milling to reduce particle size to sub-micron levels. After mixing and homogenizing, the powder is pressed using magnetic field forming presses or isostatic presses to align the magnetic domains before sintering. Our vacuum sintering furnaces operate at temperatures between 1000–1100°C, ensuring complete densification and structural integrity. Post-sintering, the magnets undergo precise CNC machining to meet exact dimensional tolerances, followed by surface treatments ranging from basic zinc plating to advanced multi-layer Ni-Cu-Ni-Au or Parylene coatings. Each step is monitored by automated systems and verified through lab testing. For instance, after GBD treatment, magnets are tested for coercivity retention at 120°C and 150°C, showing a remarkable reduction in demagnetization loss—from 12 kg to just 1.2 kg at 120°C and from 9 kg to 0.9 kg at 150°C. This data confirms the effectiveness of our diffusion process. Finally, all magnets are charged in specialized magnetizing fixtures, inspected under high-resolution imaging, and packaged with anti-static protection. The entire journey—from raw material to finished product—is governed by our core slogan: 'Strong magnets for strong products,' ensuring every magnet we deliver is engineered for excellence.
