Explore our industrial-grade, certified rare earth neodymium (NdFeB) product categories engineered for stability under extreme operating conditions.
Zhejiang Laysun Magnetics Ltd. is your trusted partner in the world of advanced magnetic solutions. Since our inception in 1999, we have grown to become a national high-tech leader in manufacturing rare earth magnets, a testament to our unwavering commitment to excellence in this niche field.
Founded at the turn of the millennium, Zhejiang Laysun Magnetics Ltd. has rapidly evolved from a visionary startup to an industry pacesetter. Our state-of-the-art factory, sprawling across 100,000 square meters in the vibrant city of Suining, Sichuan, is the heart of our operations. Here, our dedicated team of 300 employees works tirelessly to produce an impressive 5,000 tons of rare earth magnets annually.
Specializing in the development, research, production, and sales of high-performance rare earth NdFeB magnets, we cater to a diverse range of applications. Our magnets are integral to various sectors, including electric vehicles, industrial motors, computers, and consumer electronics, enhancing the efficiency and performance of these technologies.
An authoritative breakdown of metallurgical standards, thermal dynamics, coating chemistries, and the inherent structural advantages of Laysun Pro Mag Neodymium magnets.
Sintered Neodymium-Iron-Boron (NdFeB) stands as the pinnacle of contemporary permanent magnetic materials. Possessing a tetragonal crystalline structure characterized by the stoichiometry Nd₂Fe₁₄B, this configuration generates exceptionally high uniaxial magnetocrystalline anisotropy. Our proprietary metallurgical process refines the grain boundaries to minimize nucleation sites of reverse magnetic domains, allowing us to supply magnets with extreme coercivity values (Hcj) up to N52, 52nd-grade variants, and specialized thermal series including H, SH, UH, EH, and AH.
By optimizing the primary Nd₂Fe₁₄B phase alongside the grain-boundary phase (rich in Neodymium), Zhejiang Laysun Magnetics achieves exceptional magnetic alignment. This prevents internal magnetic leakage and achieves maximum energy product ratings (BHmax) exceeding 50 MGOe in commercial-scale production batches.
Because the metallic phases within raw NdFeB magnets are highly reactive and susceptible to oxidation under atmospheric moisture, we apply multi-layered protective surface finishing coatings. The primary options utilized in our modern Sichuan facility include:
Standard NdFeB alloys exhibit a linear decrease in magnetic properties as temperatures increase. To maintain maximum structural performance, our engineers integrate heavy rare earth elements (HREE) such as Dysprosium (Dy) and Terbium (Tb) through Grain Boundary Diffusion (GBD) technology. This structural innovation elevates the intrinsic coercivity (Hcj) while preventing thermal degradation, enabling reliable performance in operating temperatures exceeding 200°C.
China is home to the world’s most comprehensive supply chain network for rare earth materials, encompassing raw mining, processing, metallurgical refining, and sintered NdFeB manufacturing. Our strategic presence in Suining, Sichuan, provides direct upstream access to high-purity Neodymium oxide, Praseodymium-Neodymium (PrNd) alloy, and heavy rare earths.
This geographic location mitigates the supply volatility that commonly impacts international procurement. We integrate the entire manufacturing process—from raw vacuum induction melting to hydrogen decrepitation, jet milling, magnetic field alignment, pressing, sintering, machining, and final surface treatment—under a single, centralized quality control architecture.
This complete integration enables us to offer stable, long-term wholesale pricing structures and reliably meet production timelines for multinational customers.
