Our 5mm magnets are manufactured with ultra-precise CNC grinding and slicing technology that achieves dimensional tolerances of ±0.01mm, even for ultra-thin 5mm discs (as thin as 0.5mm). This level of precision ensures seamless integration into tight-tolerance miniaturized assemblies, reducing fit issues and assembly time for our clients in the medical device and consumer electronics sectors.

5mm磁石
Our 5mm magnets are specialized compact magnetic components designed to meet the demands of miniaturized industrial and consumer electronics, where space is limited but magnetic strength is critical. As a fully integrated manufacturer with 30 years of expertise, we produce 5mm magnets from 95%+ purity virgin neodymium-iron-boron alloy (no recycled content) using precision CNC machining that achieves dimensional tolerances as tight as ±0.01mm. Unlike generic small-sized magnets on the market, our 5mm magnets undergo rigorous multi-stage quality control to ensure consistent magnetic performance, corrosion resistance, and durability, making them the trusted choice for global manufacturers of hearing aids, micro motors, precision sensors, and wearable devices.

Precision 5mm Magnets: Compact High-Strength Solutions for Miniaturized Applications
Key Advantages of Our 5mm Magnets
Micron-Level Dimensional Precision
High Magnetic Strength in Compact Form
Despite their small size, our 5mm magnets deliver exceptional magnetic performance – with N52-grade variants achieving a magnetic energy product of up to 52 MGOe and remanence of 1.48T. This high strength-to-size ratio allows our clients to downsize their product designs without sacrificing magnetic force, a critical advantage for wearable devices, drone components, and micro-sensors where every millimeter of space matters.
Customizable Shapes & Coatings
We offer 5mm magnets in multiple standard shapes, including discs (5x1mm, 5x2mm, 5x3mm), blocks (5x5x1mm, 5x5x2mm, 5x5x5mm), and cylinders (5x5mm, 5x10mm). Every 5mm magnet is finished with a uniform Ni-Cu-Ni triple-layer electroplating (5μm per layer) that passes 720-hour salt spray tests, providing exceptional corrosion resistance for portable and outdoor applications. Custom coatings (Zn, Epoxy, Au) are also available for specialized requirements.
Technical Specifications of 5mm Magnets
The table below outlines our most commonly requested 5mm magnet configurations, available in multiple neodymium grades to suit your temperature and magnetic strength requirements. Custom sizes within the 5mm range (e.g., 5x0.5mm ultra-thin discs) are available upon request for specialized miniaturized applications.

Quality Assurance & Global Compliance for 5mm Magnets
Every batch of 5mm magnets undergoes a rigorous 14-step quality inspection process to ensure compliance with international standards. Our quality lab uses X-ray fluorescence spectrometers to verify raw material purity, digital gauss meters to test magnetic performance, and optical comparators to validate dimensional accuracy. We maintain full traceability for every 5mm magnet, from raw material lot numbers to final shipping documentation, ensuring complete accountability for our global clients. Our 5mm magnets comply with IATF 16949 (automotive), ISO 9001, REACH, RoHS 2.0, California Prop 65, and EN71, enabling seamless export to Europe, North America, Asia-Pacific, and Latin American markets.
IATF 16949:2016 ISO 9001:2015 REACH Compliant RoHS 2.0 Certified SGS 300+ Tests Passed
Packaging & Flexible Delivery for 5mm Magnets
Due to their small size and high magnetic strength, our 5mm magnets require specialized packaging to prevent loss, magnetic interference, and damage during transit. Each 5mm magnet is individually wrapped in anti-static film and placed in custom foam-lined 8-cell reinforced plastic trays (with precise 5mm slots), then packed into export-grade corrugated cartons with additional magnetic shielding layers. We offer flexible delivery options: free sample shipments (5-10 standard 5mm magnets) with 3-5 day express delivery, small-batch production (1-2 weeks lead time), and mass production (2-4 weeks lead time) with payment terms including T/T, L/C, and PayPal to suit your business model.
