Our neodymium-based super magnets deliver a maximum magnetic energy product of up to 52 MGOe (416 kJ/m³) – 30% higher than standard N42 magnets. This extreme strength allows our clients to downsize their product designs by up to 25% without sacrificing performance, reducing material costs and improving energy efficiency in high-efficiency motors, magnetic separators, and precision sensors.
Products
super magnet
Our super magnets are engineered to outperform standard permanent magnets across every critical metric – magnetic strength, temperature resistance, corrosion resistance, and dimensional precision. As a fully integrated manufacturer with 30 years of expertise, we produce super magnets from 95%+ purity virgin raw materials (no recycled content) across multiple material systems: neodymium iron boron (NdFeB), samarium cobalt (SmCo), and aluminum nickel cobalt (AlNiCo). This versatility allows us to deliver super magnets tailored to your specific needs, from compact high-strength neodymium super magnets for drone motors to high-temperature samarium cobalt super magnets for aerospace engines. Unlike generic super magnets on the market, our products undergo 14+ quality control checks to ensure consistent performance, making them the trusted choice for automotive, renewable energy, and medical device manufacturers worldwide.

Product Description
Industrial Super Magnets: Ultra-High Strength for Extreme Application Requirements
Core Advantages of Our Super Magnets
Unmatched Magnetic Strength Density
Extreme Environmental Resilience
Our super magnets are formulated to withstand the harshest operating conditions. Samarium cobalt super magnets maintain full magnetic performance at temperatures up to 350°C, while AlNiCo super magnets resist corrosion in saltwater and chemical environments for decades. All super magnets receive a uniform Ni-Cu-Ni triple-layer plating (5μm per layer) that passes 720-hour salt spray tests with zero degradation.
Precision Customization for Every Application
Our CNC machining centers produce super magnets with dimensional tolerances as tight as ±0.01mm, across sizes from 0.2mm (ultra-thin) to 300mm (large-format). We offer full customization of shapes (blocks, discs, rings, custom profiles), magnetization directions, and coatings (Ni, Zn, Epoxy, Au, Ag) to match your exact design requirements, with batch-to-batch magnetic performance variance of ≤2%.
Technical Specifications of Our Super Magnets
The table below outlines the key parameters for our three primary super magnet material systems. Custom grades, sizes, and performance characteristics are available upon request, including high-temperature, high-corrosion, and ultra-high-strength variants.

Quality Assurance & Global Compliance for Super Magnets
Every batch of super magnets undergoes a rigorous 16-step quality inspection process to ensure compliance with international standards. Our quality lab is equipped with X-ray fluorescence spectrometers (for raw material purity verification), digital gauss meters (magnetic performance testing), and coordinate measuring machines (CMM) for dimensional accuracy validation. We maintain full traceability for every super magnet, from raw material lot numbers to final shipping documentation, ensuring complete accountability for our global clients. Our super 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 & Delivery for Super Magnets
Due to their extreme magnetic strength and sensitivity to damage, our super magnets require specialized packaging to prevent magnetic interference, chipping, and demagnetization during transit. Each super 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 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.
