A comprehensive analysis of raw materials, magnetics metallurgy, global compliance, and technological integration.
Rare earth permanent magnets (specifically Sintered NdFeB) are critical to modern high-tech sectors, driving efficiency and power density. China supplies over 80% of the world's processed rare earth products. This dominance stems not only from ore deposits but from complete end-to-end refining and smelting operations.
By working directly with vertically integrated Chinese manufacturers like Zhejiang Laysun Magnetics, global buyers secure pricing stability, custom formulation capabilities, and direct access to high-demand Dysprosium (Dy) and Terbium (Tb) heavy rare earth additives, which are essential for high-temperature coercivity configurations.
Standard Neodymium magnets are susceptible to thermal degradation. High-performance industrial systems, such as wind turbine generators and EV traction motors, demand advanced grades (SH, UH, EH, AH series) capable of functioning at continuous temperatures exceeding 150°C without permanent flux loss.
Through metallurgical techniques like Grain Boundary Diffusion (GBD), we introduce Terbium or Dysprosium selectively into the boundary phases of the Nd2Fe14B crystal matrix. This process significantly increases the intrinsic coercivity (Hcj) while minimizing the reduction in remanence (Br), ensuring optimal efficiency under severe operating conditions.
A National High-Tech Leader in Sintered & Bonded Rare Earth Magnet Manufacturing.
Founded at the turn of the millennium, Zhejiang Laysun Magnetics Ltd. has rapidly evolved from a regional developer to a globally recognized supplier of magnetic systems. Our primary industrial plant spans 100,000 square meters in the specialized metal-processing zone of Sichuan, with corporate headquarters and logistical operations based in Hangzhou, China. This footprint connects Laysun directly to rich mineral supplies and advanced transport corridors.
By dedicating ourselves strictly to high-performance NdFeB magnets, we are equipped to support diverse fields including automotive steering assemblies (EPS), robotics, consumer electronics, and heavy-duty generators.
