--- Why Choose Neodymium Magnets? ---
• Superior Strength and Versatility:
Neodymium magnets are the strongest permanent magnets available today, offering exceptional magnetic strength in compact sizes—making them ideal for space-constrained applications across industries. At IT-MAG, we harness this power through advanced manufacturing techniques and precise material control. Our NdFeB magnets achieve grades as high as N55H, thanks to our proprietary Grain Boundary Diffusion (GBD) technology, which enhances coercivity without sacrificing magnetic induction. This allows devices to operate efficiently under extreme conditions—such as high temperatures or intense mechanical stress—without demagnetization. For example, in electric vehicle (EV) motors, where performance and reliability are critical, IT-MAG’s high-grade magnets deliver up to 20% higher efficiency compared to standard alternatives. The result? Longer battery life, improved acceleration, and reduced energy loss. Beyond EVs, these magnets are used in precision medical devices like MRI systems, where consistent magnetic fields ensure accurate imaging. Their versatility also extends to industrial tools, acoustic transducers, and smart home automation systems. With an annual production capacity of 3,000 tons and a factory footprint of 20,000㎡, IT-MAG ensures scalable supply without compromising on quality. Every magnet produced adheres to the mantra: 'Strong magnets for strong products.' From raw material sourcing to final packaging, every step is optimized for performance and durability. Whether you're designing a next-gen drone motor or a high-sensitivity Hall sensor, IT-MAG’s neodymium magnets provide the foundation for innovation.

--- IT-MAG's Commitment to Quality ---
• Rigorous Quality Control Processes:
At IT-MAG, quality is not an afterthought—it’s embedded in every stage of production. Our comprehensive quality control system spans from raw material inspection to final product testing, ensuring each magnet meets the highest international standards. Every batch undergoes magnetic force testing using high-precision instruments, while the chemical composition is verified via X-ray fluorescence spectrometry and inductively coupled plasma mass spectrometry (ICP-MS). We also employ a high-frequency infrared carbon and sulfur analyzer to detect trace impurities that could affect magnetic performance. Environmental resilience is rigorously tested: salt spray tests (SST), constant temperature/humidity cycles, and high-low temperature impact tests validate the durability of coatings such as Ni-Cu-Ni, Parylene, and Teflon. For instance, our Ni-Cu-Ni-Au coated magnets exceed 96 hours in PCT (pressure cooker test) and 72 hours in SST—critical for applications in harsh outdoor environments. Our lab, marked with Lab ID 03-280, operates under ISO9001, ISO14001, TS16949, and CNAS certifications, ensuring compliance with global regulatory requirements. Each magnet passes germ inspection before sintering, and final inspections include dimensional accuracy checks and surface defect analysis. We use automated forming presses and vacuum sintering furnaces to minimize human error and ensure consistency across batches. With over 17 years of experience and a team of 130 skilled professionals, IT-MAG maintains full traceability from raw material to shipment. Our production process follows a strict sequence: Raw Material → Strip Casting → Hydrogen Decrepitation → Jet Milling → Mix Milling → Pressing & Molding → Sintering → Machining → Surface Treatment → Final Inspection → Magnetization → Packaging & Delivery—all reinforced by the repeated motto: 'Strong magnets for strong products.' This unwavering focus on quality has earned us long-term partnerships with industry leaders like Ferrari and FIAT, proving that excellence is not just possible—it’s measurable.

• Grain Boundary Diffusion (GBD) Process:
IT-MAG leads the industry in advanced magnetic technologies, most notably the Grain Boundary Diffusion (GBD) process—an innovative method that revolutionizes the performance of NdFeB magnets. By selectively diffusing heavy rare-earth elements like Dysprosium (Dy) and Terbium (Tb) into the grain boundaries of sintered magnets, GBD significantly increases intrinsic coercive force without reducing magnetic induction. This breakthrough enables the production of high-coercivity grades such as N55H, N52H, and N48H—magnets previously deemed unattainable through conventional methods. The GBD process begins with pre-treatment to remove oil and scale, followed by coating Dy/Tb onto the magnet surface. The coated magnets are then subjected to vacuum heat treatment at temperatures between 700°C and 1000°C, allowing the heavy rare earths to diffuse uniformly into the intergranular regions. After milling and surface treatment, the resulting magnets exhibit enhanced resistance to demagnetization, even at elevated temperatures up to 200°C. Performance data shows that after GBD treatment, magnets retain over 90% of their magnetic strength at 150°C—compared to less than 50% for non-GBD counterparts. This makes IT-MAG’s GBD magnets ideal for high-temperature applications in EV motors, aerospace systems, and industrial drives. Moreover, GBD reduces the need for expensive heavy rare earths by up to 30%, improving cost-efficiency and sustainability. Our technical database includes over 50 magnet grades with intrinsic coercive forces ranging from 12 to 40 KOe, supporting applications from consumer electronics to medical imaging. With certifications including ISO9001, ISO14001, and IAF recognition, IT-MAG’s GBD technology is validated for reliability and scalability. Clients like Ferrari and FIAT rely on these magnets for mission-critical sensors, where failure is not an option. At IT-MAG, innovation isn’t just about pushing limits—it’s about building stronger, smarter, and more sustainable magnetic solutions. Strong magnets for strong products—this is what GBD delivers.
