Engineered for extreme compactness, reliability, and high magnetic flux density density outputs.
In the contemporary industrial ecosystem, the push for miniaturization in consumer electronics, automotive components, and aerospace actuators has generated massive global procurement demands for Ultra Thin Neodymium (NdFeB) Magnets. The technical boundaries of this material are continually pushed, with designs demanding thicknesses below 1.0mm, and in extreme electronics, down to 0.15mm.
For corporate purchasing departments and strategic technical buyers, securing continuous supplies of high-grade rare-earth magnets from direct Chinese manufacturing hubs involves analyzing critical variables such as material loss rates during wire-cutting (kerf loss), stability under high operating temperatures, and mechanical resilience against brittleness. Establishing strategic collaborations with experienced factories like Zhejiang Laysun Magnetics Ltd. provides companies with structural price protection, stable logistics pipelines, and direct engineering cooperation to resolve issues related to eddy current losses and demagnetization.
Our global operations support localized logistical solutions, customized stocking agreements, and deep material-level consulting to match specialized parameters (e.g., matching N52 performance with customized thin coatings).
Your Premier High-Tech Partner for Advanced Rare Earth Permanent Magnetic Solutions
Founded at the turn of the millennium in 1999, Zhejiang Laysun Magnetics Ltd. has evolved from a specialized metallurgical lab to a massive national high-tech manufacturing leader.

Unlocking physical boundaries: how thin neodymium permanent magnets are synthesized and machined.
To produce thin magnets with high intrinsic coercivity (Hcj) without using excessive amounts of expensive heavy rare earth metals (Dysprosium Dy, Terbium Tb), we employ advanced Grain Boundary Diffusion technology. By diffusing Dy/Tb directly along the grain boundaries post-sintering, we increase thermal stability for critical application thresholds up to 200°C.
Cutting sintered block structures into micro-foils below 0.5mm requires specialized high-speed multi-wire slicing setups and wire EDM machinery. This precision manufacturing process reduces kerf loss (the raw material disintegrated during slicing) and ensures strict tolerance control within ±0.01mm to ±0.03mm.
Thin neodymium magnets have high surface-area-to-volume ratios, making them highly susceptible to oxidation. We offer structural protective coatings: multi-layer Ni-Cu-Ni plating, high-durability epoxy resins, specialized physical vapor deposition (PVD) aluminum coatings, and custom thin rubber coatings for mechanical protection.
