Our CNC machining capabilities enable us to produce super strong magnets in nearly any shape – including blocks, discs, rings, arcs, and fully custom profiles – with sizes ranging from 0.2mm (ultra-thin precision components) to 300mm (large industrial magnets). This flexibility allows our clients to integrate super strong magnets into unique designs without compromising on magnetic force or fit.
Products
super strong magnets
Our super strong magnets are designed to empower industrial innovation by delivering extreme magnetic force in versatile, customizable form factors. As a fully integrated manufacturer with 30 years of expertise, we produce these high-performance magnets from virgin neodymium-iron-boron alloy (≥95% purity, no recycled content) using a proprietary sintering process that enhances magnetic uniformity and durability. Unlike generic super strong magnets on the market, our products are engineered to meet precise application requirements – from ultra-thin super strong magnets for medical devices to large-format variants for heavy industrial machinery. Every super strong magnet undergoes rigorous multi-stage quality control, ensuring consistent performance and compliance with global standards for automotive, renewable energy, and aerospace sectors.

Product Description
Super Strong Magnets: Custom High-Force Solutions for Industrial Innovation
Key Benefits of Our Custom Super Strong Magnets
Fully Customizable Shape & Size
Extreme Environmental Durability
Our super strong magnets are 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 marine, chemical, and outdoor applications. For high-temperature environments, our SH/UH-grade super strong magnets maintain full performance at temperatures up to 180°C, making them suitable for under-hood automotive and industrial heating systems.
Batch-to-Batch Performance Consistency
Our proprietary alloy formulation and automated production processes ensure minimal performance variance across batches of super strong magnets. We achieve ≤2% variance in remanence (Br) and coercivity (Hcj) between individual magnets, reducing waste and ensuring consistent performance in your end products – a critical advantage for high-volume manufacturing.
Technical Parameters of Super Strong Magnets
The table below outlines the standard grades and performance metrics for our super strong magnets. Custom grades, coatings (Zn, Epoxy, Au, Ag), and magnetization directions are available to meet your specific application needs, including high-corrosion, high-temperature, or precision assembly requirements.
| Grade | Typical Shape & Dimensions | Remanence (Br) mT | Coercivity (Hcj) kA/m | Max Temp (°C) | Corrosion Resistance (Salt Spray Test) |
|---|---|---|---|---|---|
| N45 | Discs (6x1-40x8mm), Blocks (15x10x5-80x40x20mm) | 1350-1370 | ≥955 | 80 | 480 Hours |
| N48H | Cylinders (8x8-30x30mm), Arcs (20x10x5-60x30x15mm) | 1380-1420 | ≥1380 | 120 | 720 Hours |
| N52 | Large Blocks (50x25x15-200x100x50mm), Custom Profiles | 1450-1480 | ≥955 | 80 | 720 Hours |
| N50SH | Precision Components (0.2mm-150mm), Industrial Magnets | 1430-1450 | ≥1620 | 150 | 720 Hours |
Global Quality Compliance for Super Strong Magnets
Every batch of super strong magnets undergoes a 14-step quality inspection process to ensure compliance with international standards. Our quality lab is equipped with X-ray fluorescence spectrometers to verify raw material purity, digital gauss meters to test magnetic performance, and salt spray chambers to validate corrosion resistance. We maintain full traceability for every super strong magnet, from raw material lot numbers to final shipping documentation, ensuring complete accountability for our global clients. Our super strong 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 Super Strong Magnets
Due to their extreme magnetic strength, our super strong magnets require specialized packaging to prevent magnetic interference, chipping, and demagnetization during transit. Each super strong magnet is individually wrapped in magnetic-shielding anti-static film and placed in custom foam inserts within 8-cell reinforced plastic trays, then packed into export-grade corrugated cartons with additional magnetic shielding layers. We offer flexible delivery options: free sample shipments (5-10 standard super strong 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.
