An in-depth look at the micro-dimensional powerhouse that drives high-frequency engineering applications worldwide.
As micro-electro-mechanical systems (MEMS), high-end wearables, and portable medical technologies shrink in dimension, the demand for high-density magnetic fields in restricted spaces has grown exponentially. The 5mm x 1mm Neodymium magnet (sintered NdFeB) represents the golden compromise between manufacturing cost, structural handling capability, and magnetic output.
Operating with a volume of just 19.63 mm³, these micro-discs generate localized magnetic field densities capable of triggering ultra-precise Hall sensors, securing micro-couplings, and delivering acoustic performance in premium acoustic transducers. Utilizing advanced grain alignment techniques, we achieve stable magnetization patterns despite the high aspect ratio.
A standard 5mm x 1mm disc in N52 Grade achieves a surface magnetic field strength exceeding 1,800 Gauss, rendering it ideal for low-clearance switching applications.
How global industries integrate the 5mm x 1mm neodymium magnet into high-reliability supply chains.
Used heavily in haptic feedback systems, smartphone camera stabilizer arrays, and magnetic charging connections inside True Wireless Stereo (TWS) earbud cases. The low profile prevents bulk while retaining strong physical attachment forces.
Integrated within smart pill micro-actuators, orthodontic appliances, and catheter guide systems. The magnets are typically coated with biocompatible Parylene or gold layers to prevent biological fluid reaction.
Acts as the triggering source for rotational encoders, position sensors, and anti-lock braking systems (ABS) micro-switches, where long-term thermal stability up to 150°C is required under severe mechanical vibrations.
Leveraging over two decades of production heritage to supply top-tier companies globally.
Founded at the turn of the millennium, Zhejiang Laysun Magnetics Ltd. has evolved from a regional magnetic workshop into a recognized high-tech pacesetter. Spanning 100,000 square meters in our manufacturing base, we balance highly optimized metallurgical processes with advanced precision slicing technologies to guarantee strict dimensional control.
For micro-scale products like the 5mm x 1mm NdFeB disk, we deploy highly automated multi-wire slicing machines. This machinery reduces kerf loss, resulting in cost savings which we pass directly to our global OEM partners. This cost-competitiveness defines our "cheap" product advantage without compromising on mechanical strength or magnetic flux consistency.
Our core values are built on four main pillars: Quality, Credibility, Technology, and Innovation. By pushing the boundaries of heavy rare-earth diffusion technologies, we continue to serve electric vehicle motor manufacturers, consumer electronics leaders, and industrial sensor designers worldwide.
A strategic technological blueprint detailing how we optimize thin-profile NdFeB magnets.
A 1mm thickness poses severe demagnetization risks due to the high self-demagnetizing field factor along the thin axis. To combat this, Laysun Magnetics uses Grain Boundary Diffusion (GBD) technology. By diffusing Dysprosium (Dy) or Terbium (Tb) selectively along the grain boundaries rather than the entire grain matrix, we enhance intrinsic coercivity (Hcj) without sacrificing remanence (Br).
This optimization allows our 5mm x 1mm magnets to maintain operational stability in harsh environments, avoiding irreversible thermal loss up to 180°C. Additionally, we enforce automated optical sorting (AOI) to detect micro-cracks and corner chips, ensuring only structurally sound parts enter the final packaging phase.
Due to the high reactivity of rare-earth elements, we apply multi-layer electroplating coatings (Ni-Cu-Ni), high-corrosion-resistance black epoxy, or thin-film Parylene C. These finishes satisfy standard salt spray testing (SST) requirements up to 96 hours.
Operating a global supply chain requires strict adherence to international standardizations. Zhejiang Laysun Magnetics maintains a robust quality management framework. We support clients through rigorous certifications and strict environmental compliance assessments.
Our quality system is verified across various demanding sectors. We hold certifications for API 6D, API 607, CE, ISO9001, ISO14001, ISO18001, and IATF 16949 (TS). All products leaving our facilities fully comply with RoHS and REACH regulations, facilitating seamless customs clearance into European and North American markets.
Headquartered in Hangzhou, China, Eneroc and Laysun are building worldwide subsidiaries and offices to serve our customers globally, ensuring local technical support and just-in-time delivery.
Direct answers from our senior materials engineering and manufacturing teams.
A standard 5mm x 1mm N52 grade Neodymium disc magnet exhibits a direct vertical pull force of approximately 130 to 180 grams when placed against a flat, ground steel plate. Actual performance will vary depending on mating material thickness, steel alloy composition, surface roughness, and air gap clearances.
For standard consumer electronics, a multi-layer Nickel-Copper-Nickel (Ni-Cu-Ni) plating offers cost-effective protection. For harsh environments exposed to chemicals, moisture, or organic fluids, we recommend Black Epoxy or Parylene coating. Parylene provides excellent pinhole-free coverage at thicknesses of just 5-15 microns, preserving tight spatial tolerances.
Our cost advantage stems from scale and technological optimization. We utilize high-yield, automated multi-wire slicers and raw material sintering systems. By producing 5,000 tons of NdFeB annually in our 100,000 m² factory, we achieve economies of scale. This allows us to supply high-performance micro-magnets without the typical pricing premium associated with custom fabrications.
Yes. For high-volume enterprise procurement, we package these micro-discs in anti-static pocket carriers on tape and reel. This setup is compatible with high-speed pick-and-place surface mount technology (SMT) machines, streamlining automated assembly processes.
