Premium selection of customized NdFeB magnets engineered to meet exact industrial tolerances and high demagnetization resistance.
Magnetization of steel products involves transforming isotropic magnetic domains within the alloy lattice structure into oriented, highly magnetic states. While standard carbon steel can be magnetized temporarily, the production of high-strength permanent assemblies requires advanced rare earth alloys, primarily Neodymium-Iron-Boron (NdFeB). Sintered NdFeB is the most powerful permanent magnetic material available globally, characterized by its high remanence ($B_r$), high coercivity ($H_{cj}$), and maximum energy product ($(BH)_{max}$).
As a leading Chinese manufacturer, Zhejiang Laysun Magnetics Ltd. utilizes advanced vacuum induction melting (VIM), strip casting, and hydrogen decrepitation to ensure ultra-fine crystal grain control. This control is critical for preventing internal structural defects and ensuring that the final steel and neodymium assemblies demonstrate excellent thermal stability and long-term durability in high-vibration applications.
We blend 25 years of engineering heritage with a modernized 100,000 m² smart factory layout.
Founded in 1999, we have achieved national high-tech enterprise recognition. With over two decades of refinement, we guide clients through composition, prototyping, and large-scale industrialization.
Our Suining, Sichuan facility outputs 5,000 tons of rare earth magnets annually. This massive scale provides consistent pricing stability and avoids material bottlenecks for large commercial projects.
We leverage advanced metallurgical technology to supply standard N35 to ultra-high performance AH grades. Our team specializes in preventing atmospheric degradation via chemical plating methods.
