Our small strong magnets leverage high-grade NdFeB material with purity ≥95% (no recycled materials) to achieve remanence up to 1.5T – far exceeding generic miniature magnets on the market. Even at sizes as small as 0.2mm, these magnets maintain exceptional coercivity, ensuring reliable performance in tight spaces where larger magnets cannot fit.

Small Strong Magnets: Compact Power for Precision Industrial Applications
Key Advantages of Our Small Strong Magnets
Unmatched Compact Power
Precision Machining & Tolerance
Every batch of small strong magnets is processed with CNC grinding centers that control dimensional tolerance to ±0.01mm. This level of precision ensures seamless integration into your miniaturized assemblies, reducing fit issues and improving production efficiency. We support custom shapes (tapered, threaded, stepped) for unique small strong magnet applications.
Robust Corrosion Protection
Our small strong magnets feature a triple-layer Ni-Cu-Ni electroplating (5μm per nickel layer) applied via fully automated lines, providing superior corrosion resistance. The uniform coating prevents rust and oxidation, even in harsh environments like automotive electronics or outdoor sensors – critical for small strong magnets that operate in confined, hard-to-maintain spaces.
Technical Specifications of Small Strong Magnets
The table below outlines our standard range of small strong magnets, covering common sizes and grades to suit diverse industrial needs. Custom specifications (size, grade, coating) are available upon request, with fast prototyping for small batch orders.

|---|---|---|---|---|---|
| N42 | 0.2-15 | 1300-1320 | 80 | Ni-Cu-Ni, Zn | Micro-sensors, small DC motors |
| N48H | 0.5-20 | 1380-1420 | 120 | Ni-Cu-Ni, Epoxy | Medical devices, precision actuators |
| N52SH | 1.0-25 | 1430-1480 | 150 | Ni-Cu-Ni, Au | High-temperature small motors, aerospace components |
| SmCo28 | 0.8-30 | 1050-1100 | 350 | Epoxy, Ni | High-temp small strong magnets for industrial sensors |
Quality Assurance for Small Strong Magnets
Our small strong magnets undergo over 10 quality control checks throughout production, from raw material spectrometry to final magnetic performance testing with advanced X-ray thickness gauges and high-temperature test chambers. We hold IATF 16949 (automotive) and ISO 9001 certifications, and all small strong magnets comply with REACH, RoHS, and CP65 standards – ensuring seamless export to EU, US, and Asian markets.
IATF 16949:2016 ISO 9001:2015 REACH & RoHS Compliant SGS 300+ Test Passed
Packaging & Delivery for Small Strong Magnets
To protect the delicate precision of our small strong magnets during shipping, we use 8-cell reinforced inner boxes (individually segregating each magnet) paired with export-grade outer cartons – dual-layer protection that prevents chipping, scratching, or magnetic damage. We offer free sample delivery for small strong magnets (up to 10 pieces), fast prototyping (3-5 days), and flexible payment terms to support your small-batch or mass production needs.
