Whether it’s a small batch for prototyping or large-scale production, IT-MAG combines technical expertise, advanced manufacturing, and agile R&D to turn your concept into a high-performance reality. With a proven track record and a client-first philosophy, we are more than just a supplier—we’re your strategic partner in innovation.
--- Our Advanced Production Techniques ---
• Grain Boundary Diffusion Technology:
At IT-MAG, we pioneer the use of Grain Boundary Diffusion (GBD) technology—a breakthrough process that significantly enhances the coercivity of sintered NdFeB magnets without sacrificing magnetic strength. This proprietary method involves coating the magnet surface with heavy rare-earth elements such as Dysprosium (Dy) or Terbium (Tb), followed by vacuum heat treatment at temperatures between 700°C and 1000°C. The diffusion of these elements into the grain boundaries effectively increases resistance to demagnetization, enabling the production of high-grade magnets like N55H and N52UH—grades previously unattainable through conventional methods. Our GBD process has been rigorously tested under extreme thermal conditions: at 120°C, post-GBD magnets show a residual demagnetization loss of just 1.2% compared to 12% before treatment; at 150°C, the improvement is even more dramatic—reducing loss from 9% to 0.9%. This level of performance makes our magnets ideal for applications requiring stable operation in high-temperature environments, such as permanent magnet motors in EVs and industrial automation systems. Furthermore, our ability to tailor rare earth content—offering options labeled as 'Heavy Rare Earth Low' or 'Heavy Rare Earth Free'—supports both cost optimization and sustainability goals. Backed by extensive lab testing using X-ray fluorescence spectrometry, inductively coupled plasma analysis, and salt spray testing, our GBD-processed magnets consistently exceed industry benchmarks. By integrating this advanced technology into our full production chain—from strip casting to final magnetization—we ensure that every magnet delivered embodies the core principle: Strong magnets for strong products.
--- Product Range and Coating Options ---
• Variety of Neodymium Magnet Types:
IT-MAG offers a comprehensive range of neodymium magnets and magnetic assemblies designed to meet diverse engineering demands. From standard rectangular and disc magnets to complex multi-pole configurations and fully integrated magnetic sub-assemblies, our product portfolio supports applications across sectors such as PM motors, loudspeakers, MRI machines, construction equipment, and precision sensors. We produce magnets in grades ranging from N30 to N55, with customizable shapes, dimensions, tolerances down to ±0.05mm, and magnetic orientations including axial, radial, and multi-directional. Our coating options are equally robust and application-specific. For instance, Ni-Cu-Ni provides excellent corrosion resistance with ≥48 hours SST and PCT, making it ideal for outdoor or humid environments. Electroless Ni offers superior uniformity and durability, while Parylene coating delivers pore-free protection against corrosive vapors and solvents—perfect for medical implants. Epoxy resin coatings offer exceptional binding force and resistance to moisture and salt spray, suitable for marine and aerospace uses. Teflon-coated magnets stand out for their self-lubrication and high-temperature tolerance, commonly used in robotic joints and high-friction mechanisms. Even specialized finishes like Ni-Cu-Ni-Au and Ni-Cu-Ni-Sn cater to decorative and conductive needs in consumer electronics and smart devices. Each coating undergoes strict quality checks via salt spray tests, humidity chambers, and infrared carbon/sulfur analysis. With over 17 years of experience, IT-MAG continues to innovate—not just in material science, but in delivering tailored solutions where form, function, and longevity converge. Every magnet we produce is engineered to be stronger, smarter, and more reliable—because strong magnets make strong products.
--- Success Stories and Client Collaborations ---
• Innovative Solutions for Automotive Industry:
One of IT-MAG’s most notable success stories lies in its collaboration with Ferrari on brake-Hall sensor systems for high-performance electric vehicles. The challenge was clear: develop a compact, high-sensitivity magnetic assembly capable of operating reliably under intense vibration, high temperature (up to 150°C), and rapid dynamic changes. Traditional NdFeB magnets would lose up to 15% of their magnetic strength under such conditions, risking sensor failure. IT-MAG responded by designing a custom magnetic assembly using GBD-processed N52H-grade magnets with a Ni-Cu-Ni-Au coating for enhanced conductivity and corrosion resistance. The result? A sensor system that maintained 99.7% signal fidelity even after 10,000 hours of continuous operation under simulated race conditions. This solution was later adopted by FIAT for throttle-Hall sensors, where similar performance demands required ultra-stable magnetic fields. Working closely with brands like MAGNEN and ARELL, IT-MAG provided not only the magnet components but also full integration support, including dimensional validation, thermal cycling testing, and electromagnetic compatibility (EMC) assessments. These partnerships underscore IT-MAG’s role as a technology enabler—delivering not just materials, but complete, validated solutions. With certifications from ISO, IAF, and CNAS, and a dedicated R&D team focused on real-world application challenges, IT-MAG continues to power innovation in the global automotive industry. Our mission remains unchanged: Strong magnets for strong products.
• Partnerships with Leading Global Brands:
IT-MAG’s reputation extends far beyond regional markets—our magnetic solutions have become integral components in products used by some of the world’s most respected brands. One standout example is our long-term partnership with a leading global manufacturer of industrial power tools, where we supplied custom NdFeB magnetic assemblies for motor rotors in cordless drills and saws. The client required magnets that could withstand repeated thermal cycling, mechanical shock, and exposure to dust and oil. After rigorous evaluation, IT-MAG delivered a solution based on GBD-optimized N48H magnets with an epoxy resin coating, offering ≥72 hours of salt spray resistance and superior adhesion. Field tests confirmed a 40% reduction in motor failure rate compared to previous models. Another milestone came when we partnered with a top-tier medical device company developing a next-generation MRI-compatible positioning system. Here, we provided low-outgassing, non-magnetic interference NdFeB assemblies with Parylene C coating, meeting stringent biocompatibility and sterilization requirements. These collaborations highlight IT-MAG’s ability to adapt to highly regulated, safety-critical industries. With over 17 years of history, 130 employees, and a vertically integrated production line—including vacuum sintering furnaces, jet mills, and automated forming presses—we maintain full control over quality and delivery timelines. Our clients trust us not only for our technical excellence but also for our responsiveness and transparency. Whether it’s a prototype request or mass production, IT-MAG delivers with precision, speed, and integrity—proving once again that strong magnets truly do make strong products.
