Product Overview
The 10 mm N52 Neodymium Magnet is a compact yet powerful disc magnet engineered for industrial and OEM applications where small size but strong magnetic force are required. Its modest 10 mm diameter makes it ideal for incorporation into sensors, small motor components, magnetic assemblies, or compact fixtures - while the high-energy N52 NdFeB material ensures strong, reliable magnetic performance even in demanding assemblies.
Specifications
- Material: Sintered Nd-Fe-B (Rare-earth Neodymium-Iron-Boron)
- Grade: N52 - high magnetic energy, suitable for demanding magnetic requirements.
- Shape: Disc / Cylinder (10 mm diameter) - standard thickness options from 2 mm to 10 mm (or as required by customer). Similar size magnet 10 mm × 3 mm produces ~2.25 kg pull-force.
- Magnetization: Axial (through thickness) - giving strong flux across the flat faces.
- Coating: Standard Ni-Cu-Ni (nickel-copper-nickel) plating, providing corrosion resistance and surface durability.
- Tolerance: ±0.1 mm (custom tolerances available) ALB Materials Inc+1
- Typical Pull Force: Example 10 mm × 3 mm (N52 disc) ~2.25 kg (5 lbs) on flat low-carbon steel surface.
- Operating Temperature (standard): Up to ~80 °C for standard N52 coating; higher temperature grades available upon request.
Key Features & Industrial Applications
- Compact size, high magnetic energy: The small 10 mm disc delivers considerable magnetic flux relative to its size - useful for small motor modules, sensor housings, magnetic switches, or precision fixture components.
- Flexible integration: Axial magnetization and standard disc shape mean easy design-in for engineers - simply embed or mount in housing, PCB, mechanical module or assembly.
- Reliable surface protection: Nickel-based plating helps resist corrosion, wear, and environmental exposure - suitable for industrial or consumer-product applications.
- Wide usage scenarios: Common uses include small DC motors, magnetic couplings, rotary encoders, proximity sensors, magnetic closures, sample-holding fixtures, and compact magnetic assemblies.
Why It Matters for Industrial Buyers
- Scalable supply: We support bulk industrial orders, ensuring consistent magnetic performance and tight dimensional tolerance across batches - essential for mass production.
- Custom magnet service: If standard thickness or magnetization doesn't match your design, we can produce custom neodymium magnets with modified size, polarity, coating or tolerance per your drawing.
- Quality assurance: Each batch undergoes magnetic flux testing, dimension inspection, and coating quality checks - you receive inspection reports along with the shipment, which helps with QC and traceability.
- Cost-effective design integration: Using a small, powerful disc magnet like this reduces material waste and simplifies mechanical design - especially when embedding inside compact devices or assemblies.
Packaging & Shipping
For safety and to avoid magnet-to-magnet attraction, magnets are individually separated with non-magnetic spacers and packed in magnet-safe cartons. For large orders, anti-magnetic transport packaging is standard, protecting both magnets and surrounding items during shipment.
FAQ
Q1: Can you supply other sizes besides 10 mm?
Yes - we support custom disc magnets and blocks of various sizes, thicknesses and magnetization directions.
Q2: Can you supply higher-temperature tolerant magnets?
Yes - besides standard N52, we offer high-temperature variants (M-, H-, SH-grades) with appropriate coatings for elevated thermal resistance.
Q3: What is the minimum order quantity (MOQ)?
For standard 10 mm magnets, small sample orders are supported. For bulk industrial orders we offer tiered pricing - contact us for detailed quotation.
Q4: Can I get magnetic property and dimensional test reports?
Absolutely - every batch is tested and we can provide test data (residual flux, pull force, dimensional tolerance, coating thickness) for your QC files.
