Explore our top-performing custom cylinder, block, pot, and embedded flat magnetic components designed for high-shear industrial applications.
How modern miniature, flat magnetic architectures are transforming automation, precast civil engineering, and micro-device integrations.
Utilizing vacuum induction melting and customized strip casting, modern small flat magnets leverage NdFeB (Neodymium Iron Boron) and SmCo (Samarium Cobalt) configurations to output unmatched coercivity and flux density profiles within sub-millimeter tolerances.
Operating environments in heavy industries demand resilience. High-quality small flat magnets now feature advanced surface modification options including multi-layer Ni-Cu-Ni, Epoxy resin, Zinc, and Chrome plating, preventing oxidation up to continuous 350°C cycles.
Flat magnet profiles maximize surface area contact to deliver optimized normal clamping force. Our proprietary cup and shuttering designs encase these magnets in carbon steel shells to direct magnetic flux lines directly to the work surface, increasing hold efficiency up to 200%.
Selecting the appropriate magnetic compound based on thermal limits, mechanical shear demands, and corrosive exposures.
| Magnetic Material Class | Common Grade Range | Remanence (Br) | Coercivity (Hcb) | Max Energy Product (BHmax) | Peak Temperature Limit |
|---|---|---|---|---|---|
| NdFeB (Neodymium) | N35 - N52, AH Series | 1.17 - 1.48 T | ≥ 828 kA/m | 263 - 414 kJ/m³ | 80°C to 240°C |
| SmCo (Samarium Cobalt) | YXG-24 to YXG-32 | 0.90 - 1.15 T | ≥ 640 kA/m | 180 - 240 kJ/m³ | 250°C to 350°C |
| Ferrite / Ceramic | Y25, Y30, Y35 | 0.35 - 0.43 T | ≥ 170 kA/m | 26 - 36 kJ/m³ | 250°C |
| Alnico (Cast/Sintered) | Alnico 5 to Alnico 9 | 0.60 - 1.35 T | ≥ 48 kA/m | 40 - 80 kJ/m³ | 450°C to 550°C |
Our flat pot magnets utilize high-grade carbon steel cups configured as magnetic circuits (Halbach array derivatives). By encasing the rare-earth core, the non-working face flux is redirected to the work surface, multiplying local vertical holding capability.
Exported batches maintain structural flatness up to 3 microns. This avoids micro-gaps when paired with flat industrial steel poles, guaranteeing zero loss of designed shear capacity under vibration stress.

In modern automated precast concrete factories, manual placement of formwork magnets is being replaced by heavy gantry robots. Future small flat magnets and shuttering boxes are designed with standardized robotic gripping interfaces, allowing mechanical arms to pick, place, activate, and release the magnetic hold based on CAD architectural files.
Traditional high-coercivity NdFeB magnets rely on Dysprosium (Dy) and Terbium (Tb) to maintain magnetic properties at high temperatures. Due to the scarcity and cost of these heavy rare earth elements, QCM's technical roadmap focuses on grain boundary diffusion (GBD) processes. This allows us to supply small flat magnets with extreme temperature resistance while lowering raw material costs for wholesale buyers.
Concrete slurries contain corrosive chemical additives. To ensure a lifecycle of over 10 years, flat industrial magnets now feature advanced hybrid coatings. Beyond standard Ni-Cu-Ni, our development of Everlube, Teflon, and chemical-vapor-deposited (CVD) Parylene coatings offers unprecedented resistance against concrete adhesion, high-pressure washes, and alkaline degradation.
