Optimized permanent magnet technologies engineered for heavy industrial, turbine, and electric motor integration.
New York state boasts a highly advanced industrial sector driven by innovations in robotics, aerospace, medical technologies (such as MRI manufacturing in Upstate NY), and the rapid transition toward electric mobility and offshore wind energy. To support these clean technology initiatives, reliable access to high-performance sintered NdFeB (Neodymium Iron Boron) magnets is critical.
Upstate New York, particularly regions around Rochester, Syracuse, and Buffalo, has reemerged as a high-tech manufacturing corridor. This industrial base requires highly specialized magnetic grades like N52, 50M, 48H, 45SH, 42UH, and 38EH, which can withstand elevated operational temperatures without significant demagnetization loss. From local precision motor manufacturers to defense contractors on Long Island, the specification standards for rare earth magnets require extreme dimensional accuracy and coating stability.
Additionally, the New York State Energy Research and Development Authority (NYSERDA) continues to fund grid-scale energy storage and offshore wind generation projects along the Atlantic coast. Zhejiang Laysun Magnetics Ltd. provides the critical supply security, technical capabilities, and advanced alloy properties required to feed this localized manufacturing resurgence.
In the modern geopolitical landscape, global enterprise procurement departments must navigate complex supply chains to secure vital raw materials. Standard neodymium magnets are highly vulnerable to localized raw material bottlenecks. Thus, tier-one purchasing officers in New York prioritize direct-from-manufacturer relationships that offer clear material traceability and robust production capabilities.
Working directly with a high-capacity producer like Zhejiang Laysun Magnetics ensures that engineers and procurement managers receive custom-fabricated magnetic materials with verified testing parameters, including hysteresis loop analysis, magnetic flux mapping, and salt spray corrosion resistance documentation.
To support New York's sophisticated just-in-time (JIT) manufacturing systems, we coordinate efficient multimodal logistics pathways. Whether shipping to the Port of New York and New Jersey or utilizing air freight channels via JFK International Airport, our logistics partners ensure seamless customs processing and continuous compliance with U.S. Federal regulations.
Zhejiang Laysun Magnetics Ltd. is a national high-tech enterprise specializing in the research, development, production, and sale of advanced rare earth NdFeB permanent magnets. Established in 1999, the company has dedicated over two decades to pushing the physical limits of magnetic performance and manufacturing consistency.
Our expansive production facility covers 100,000 square meters in Sichuan, a region globally recognized for its abundant rare earth mineral deposits. By locating our production directly near raw processing zones, we secure stable access to critical heavy rare earth elements like Dysprosium (Dy) and Terbium (Tb), which are crucial for maintaining high thermal stability in magnets. With a workforce of 300 highly trained technicians and quality controllers, we produce 5,000 tons of high-grade rare earth magnets annually.

Pioneering advancements in grain boundary engineering and metallurgical refining to support next-generation technologies.
We produce ultra-reliable neodymium magnets for Automotive Electric Power Steering (EPS) systems and EV traction motors. Utilizing Grain Boundary Diffusion (GBD) technology, we reduce heavy rare earth content while achieving high intrinsic coercivity (Hcj), ensuring steady torque and operation up to 200°C.
From servo motors to robotic joints, high torque density is essential for modern robotics. Our custom-machined block and arc segments allow engineers to construct smaller, lighter motors with higher magnetic flux density, optimizing overall system response times and positional accuracy.
Direct-drive wind generators demand massive quantities of large, highly uniform permanent magnets. Our sintered NdFeB blocks utilize specialized multi-layer nickel and epoxy coatings (exceeding 1000-hour salt spray tests) to survive the harsh coastal environments of the Northeast US.
As the global demand for rare earths increases, the industry is transitioning toward reducing reliance on heavy rare earths (HRE) such as Dysprosium and Terbium. Zhejiang Laysun Magnetics is at the forefront of this shift, researching and implementing new crystal grain refinement processes. By controlling grain boundary thickness and orientation at the sub-micron level, we aim to produce high-coercivity magnets with minimal HRE content, offering more cost-effective solutions to our clients in New York and worldwide.
Furthermore, our technical roadmap focuses on optimizing automated optical inspection (AOI) systems and advanced helium-leak testing for magnetic assemblies. This ensures that every magnetic component shipped to New York's aerospace and biomedical facilities meets the most demanding quality and performance standards.
At Zhejiang Laysun Magnetics, quality is not simply a metric—it is the core foundation of our engineering process. Our facilities operate under strict internationally recognized quality systems, including ISO 9001 and ISO 14001, to ensure environmental compliance and process control. We are also aligned with automotive supply standards to meet the requirements of advanced vehicle manufacturers.
Our magnets are fully compliant with RoHS and REACH regulations, confirming that they are free of restricted hazardous substances and safe for integration into medical devices, consumer products, and clean energy systems. We perform intensive batch verification utilizing computerized testing benches, documenting essential properties such as flux density (B), field strength (H), and demagnetization profiles before any shipment leaves our warehouse.

Our factories utilize precise sintering and machining technologies to supply magnets with extremely low tolerances, ensuring reliability for medical applications in New York and globally.
Expert answers regarding material parameters, coating options, and delivery logistics to New York.
The maximum operating temperature depends on the specific grade. Standard Neodymium (N) grades operate up to 80°C (176°F). However, we produce high-coercivity grades including M (up to 100°C), H (up to 120°C), SH (up to 150°C), UH (up to 180°C), EH (up to 200°C), and AH (up to 220°C). By optimizing the alloy composition, we ensure stability at higher temperatures.
Neodymium magnets are prone to corrosion if unprotected. We offer several options: Nickel-Copper-Nickel (Ni-Cu-Ni), which is standard; Zinc (Zn) coating for basic protection; and Epoxy or Parylene coatings for high moisture resistance. For marine applications, we recommend our specialized multi-layer epoxy coating, which is tested to withstand over 1,000 hours of salt spray exposure.
Yes, we specialize in high-tolerance custom machining. Using diamond grinding, wire EDM, and CNC machining, we can produce complex shapes and configurations. We also specialize in magnetic assemblies, bonding magnets directly to steel shafts, rotors, or housings to simplify integration into your production line.
