Explore our high-performance permanent rare earth NdFeB magnets, engineered for extreme mechanical stability and high coercivity applications.
Sintered Neodymium-Iron-Boron (NdFeB) magnets stand as the absolute zenith of modern permanent magnetic materials, possessing an unparalleled maximum energy product (BHmax) that spans from 30 to 52 MGOe (and up to 55 MGOe in specialized laboratory settings). The mechanical structure consists of a matrix containing the highly magnetic Nd2Fe14B tetragonal crystalline phase.
Our engineered alloy designs utilize advanced Grain Boundary Diffusion (GBD) methods. This technical advancement allows us to strategically diffuse heavy rare earths (Dysprosium, Dy, or Terbium, Tb) into the crystal boundaries. The result is a substantial optimization of intrinsic coercivity (Hcj) without sacrificing remanence (Br), ensuring our magnet solutions perform reliably under operating conditions exceeding 200°C.
Whether applied in traction motors for electric vehicles or highly sensitive voice coil actuators in consumer electronics, our custom neodymium formulations deliver optimal flux density, corrosion resistance via customized multi-layer coatings, and long-term demagnetization resistance.
Established at the turn of the millennium, Zhejiang Laysun Magnetics Ltd. has matured from a regional rare earth supplier into a globally recognized authority in the high-performance magnetic materials market. Headquartered in Hangzhou, China, our specialized manufacturing complex spans over 100,000 square meters in Suining, Sichuan—strategically situated close to key raw material reserves to guarantee supply chain integrity and stability.
We employ more than 300 highly qualified materials scientists, metallurgical engineers, and production experts. This centralized workforce manages our annual output of 5,000 tons of high-grade sintered NdFeB magnets. We support international industries ranging from aerospace and e-mobility to modern consumer electronics.
By executing strict quality controls, from the initial vacuum induction melting through atomization, alignment, sintering, and post-machining processes, we ensure that every magnet delivered satisfies international engineering tolerances.
Leveraging Neodymium magnet energy density to drive performance across the world's most demanding sectors.
Sintered NdFeB magnets are integral to permanent magnet synchronous motors (PMSM) within electric vehicle drive units and highly responsive Electronic Power Steering (EPS) units, reducing energy draw while maintaining optimal torque delivery.
Brushless DC (BLDC) motors driving robotic joints and multi-rotor drone propulsion rely on the massive power-to-weight ratio of high-grade neodymium ring and arc magnets to maximize operational efficiency and structural payload limits.
From micro-speakers and sensory haptic feedback components to magnetic ring assemblies compatible with Magsafe mobile accessories, we deliver extreme dimensional tolerances for consumer electronics.
