Micro-sized sintered Neodymium-Iron-Boron (NdFeB) magnets, measuring a mere 2mm in diameter by 1mm in thickness, represent the cutting edge of modern powder metallurgy and miniaturization. At these dimensions, standard manufacturing techniques yield to extreme micromanufacturing processes. These sub-millimeter tolerances are vital for high-tech integrations where dimensional deviations directly compromise performance.
Our 2mm x 1mm magnets are characterized by high remanence (Br), coercivity (Hcb/Hcj), and maximum energy product (BH)max. They provide exceptionally dense magnetic fluxes relative to their miniscule volume. They are widely specified in components where space is at a premium—such as ultra-compact haptic feedback systems, medical implants, high-fidelity micro acoustic drivers, and micro-electromechanical systems (MEMS).
Understanding the physical and magnetic constraints is vital for component layout design. The table below represents the core parameters of our high-precision micro-magnets across typical industrial grades.
| Material Grade | Remanence (Br) | Coercivity (Hcb) | Intrinsic Coercivity (Hcj) | Max Energy Product (BH)max | Max Operating Temp |
|---|---|---|---|---|---|
| N35 | 1.17 - 1.22 T (11.7 - 12.2 kG) | ≥ 868 kA/m (≥ 10.9 kOe) | ≥ 955 kA/m (≥ 12 kOe) | 263 - 287 kJ/m³ (33 - 36 MGOe) | 80°C / 176°F |
| N52 | 1.43 - 1.48 T (14.3 - 14.8 kG) | ≥ 876 kA/m (≥ 11.0 kOe) | ≥ 876 kA/m (≥ 11 kOe) | 398 - 414 kJ/m³ (50 - 52 MGOe) | 80°C / 176°F |
| N38SH | 1.22 - 1.25 T (12.2 - 12.5 kG) | ≥ 907 kA/m (≥ 11.4 kOe) | ≥ 1592 kA/m (≥ 20 kOe) | 287 - 310 kJ/m³ (36 - 39 MGOe) | 150°C / 302°F |
| N35UH | 1.17 - 1.22 T (11.7 - 12.2 kG) | ≥ 876 kA/m (≥ 11.0 kOe) | ≥ 1990 kA/m (≥ 25 kOe) | 263 - 287 kJ/m³ (33 - 36 MGOe) | 180°C / 356°F |
| N30EH | 1.08 - 1.13 T (10.8 - 11.3 kG) | ≥ 812 kA/m (≥ 10.2 kOe) | ≥ 2387 kA/m (≥ 30 kOe) | 223 - 247 kJ/m³ (28 - 31 MGOe) | 200°C / 392°F |
*Note: For applications operating in environments subject to sustained thermal stress, selecting custom high-coercivity grades (SH, UH, EH, or AH) prevents irreversible demagnetization losses.*
Since our inception in 1999, Zhejiang Laysun Magnetics Ltd. has evolved from a visionary developer to a national high-tech manufacturing leader in rare earth magnets. Sprawling across a state-of-the-art 100,000 square meter factory facility in Suining, Sichuan, and supported by corporate headquarters in Hangzhou, Zhejiang, we leverage advanced metallurgical technologies and high-capacity processing equipment to deliver premium-grade NdFeB magnets globally.
We do not simply export stock shapes; we partner with your engineering teams to deliver custom components optimized for your application's unique geometry, thermal parameters, and mechanical constraints.
Sourcing micro-magnets from China represents a strategic advantage when choosing Zhejiang Laysun Magnetics Ltd. The production of a 2mm x 1mm magnet requires advanced wire-electrode cutting (EDM) or high-speed multi-wire slicing technology, combined with precise grinding. These processes require extensive capital investment, stable chemical processes, and highly skilled engineering staff.
Precision is not negotiated; it is engineered. We use automatic inner aperture slicing machines and modern double-disk grinders to maintain thickness tolerances to +/-0.01mm, preventing chips, cracks, or structural degradation in micro sizes.
Micro-magnets possess a high surface-area-to-volume ratio, making them susceptible to environmental oxidation. We utilize automated chemical vapor deposition (CVD) and physical electroplating for uniform coverage down to the microscale.
Every single 2mm x 1mm magnet batch passes through automated flux testing devices. Inconsistent magnetic outputs are filtered, ensuring that only components matching the design specifications reach your assembly line.
As technological hardware shrinks, engineers demand stronger forces in compact physical structures. The NdFeB 2mm x 1mm disc magnet is highly efficient for high-density layouts. Some typical applications include:
High-precision servo actuators and joint encoder magnets.
Micro brushless motors and gimbal stabilization systems.
Sensors, EPS motors, and high-temperature magnetic components.
High-durability brushless motors and high-torque couplings.
Acoustic speakers, smart tactile devices, and phone accessories.
Highly efficient compressor motors and smart locks.
For large-scale B2B electronics and industrial supply chains, documentation compliance is as critical as hardware tolerances. We adhere to high quality control standards to simplify verification audits for our partners.
We supply complete documentation packs for our 2mm x 1mm magnets, including material certifications, demagnetization curves, and RoHS/REACH declarations. Our global support channels facilitate rapid customs clearance, packaging optimized for international logistics, and dynamic technical support directly from our R&D team.
API 6D, API 607, CE, ISO9001, ISO14001, ISO18001, and IATF 16949 for automotive-grade permanent magnet manufacturing.
Headquartered in Hangzhou, Zhejiang, and backed by our massive manufacturing site in Suining, Sichuan, Zhejiang Laysun Magnetics Ltd. provides worldwide support for all procurement demands. Through integrated multimodal transport networks, we arrange safe air freight, bulk maritime shipping, and door-to-door express parcel deliveries.
Because micro Neodymium magnets pose safety risks to aviation due to magnetic flux leakage, we use specialized shielding packaging (using sheet metal boundaries) to guarantee shipping compliance. This allows us to supply high-performance rare earth solutions quickly, wherever your operations are based.
Whether you require a custom grade formulation, tight dimensional tolerances, or specialized environmental coating configurations, the engineers at Zhejiang Laysun Magnetics Ltd. are ready to assist. Contact us today, and we will send a detailed response within 24 hours.
