Safety CertificationsThe global transition toward green mobility, automated manufacturing, and smart energy infrastructure has positioned Neodymium-Iron-Boron (NdFeB) permanent magnets as a cornerstone critical raw material. Accounting for over 60% of the market share in advanced permanent magnetic materials, sintered neodymium magnets provide the highest energy-to-volume ratio ($BH_{max}$) currently feasible for industrial applications.
Today, the raw material supply chain of neodymium is intrinsically tied to global rare earth element (REE) mining and processing nodes. As a leading manufacturer, QCM Magnet coordinates with state-of-the-art smelting operations to secure stable supply pools of PrNd (Praseodymium-Neodymium) metal, protecting our long-term wholesale clients from volatile price index spikes on the Shanghai Metals Market (SMM) and other critical metals exchanges.
By implementing a highly automated sinter-pressing and wire-cutting processing pipeline, our facilities ensure that dimensional deviations remain under ±0.05 mm, which is vital for integration into high-speed automation tooling and modern electric vehicle powertrains.
Modern industrial specifications demand high thermal resistance without using excessive amounts of expensive Heavy Rare Earths (HREEs) like Dysprosium (Dy) or Terbium (Tb). GBD technology allows our engineers to precisely diffuse Dy or Tb only along the grain boundaries of the sintered microstructure, improving coercivity ($H_{cj}$) while maintaining a high remanence ($B_r$) rating and minimizing raw material costs.
Uncoated NdFeB is highly susceptible to atmospheric oxidation. Our chemical treatment lines utilize advanced multi-layer electroplating processes, including Ni-Cu-Ni, Zn, Gold, and organic Epoxy seals. For marine environments and offshore structural components, we offer custom-engineered Teflon and Everlube coatings that pass the rigorous 96-hour ASTM B117 salt spray tests.
The carbon footprint of raw REE mining makes NdFeB recycling a highly scrutinized supply metric. QCM Magnet is actively developing closed-loop recycling frameworks where post-industrial magnet scrap and structural elements are recovered, hydrometallurgically refined, and blended into new powder batches, lowering emissions and stabilizing long-term contract pricing.
QCM Magnet specializes in offering complete magnetic fixing solutions for the production of precast concrete components. Our primary products include Shuttering Magnets and their corresponding accessories, Formwork Magnets, Magnetic Chamfering Strips, and various pre-embedded insert magnets. Utilizing magnetic fixing in precast concrete component production prevents damage to the casting platform, enhances work efficiency, reduces labor costs, and promotes economic efficiency as the magnetic fixing devices are reusable.
Using our expertise in magnetic components and our extensive experience in supporting the production of precast components, we have developed numerous new and practical magnetic fixing products. Our products come with complete specifications, excellent quality, ease of operation, and long service life. Additionally, we can promptly customize a variety of magnetic fixing parts to meet the diverse needs of our customers.

Purchasing wholesale neodymium requires an understanding of how raw materials and manufacturing choices affect the final price per unit. The table below outlines how specific requirements influence production costs, helping you optimize your ordering strategy:
| Cost Factor | Key Metrics / Grade Variations | Pricelist Impact | Optimized Sourcing Recommendation |
|---|---|---|---|
| Raw Materials (PrNd Oxide) | Market rate of PrNd metal (per kg) | 60% - 70% of unit price | Establish annual blanket purchase orders to lock in raw material prices. |
| Intrinsic Coercivity ($H_{cj}$) | Standard (N) vs. High Temp (M, H, SH, UH, EH, AH) | +15% to +80% surcharge | Use standard grades (up to 80°C) unless your system operates in high-heat environments. |
| Surface Plating Options | Uncoated, Zinc, Ni-Cu-Ni, Epoxy, Teflon | +5% to +20% variation | Choose Zinc for cost-sensitive indoor setups; use Epoxy/Teflon for high-humidity or marine applications. |
| Dimensional Tolerances | Standard (±0.1 mm) vs. High Precision (±0.01 mm) | +10% to +35% variation | Specify tight tolerances only for critical contact points, allowing standard tolerances elsewhere to control costs. |
Whether you are retrofitting concrete formwork platforms or building high-speed mechanical drives, QCM Magnet delivers integrated solutions that lower structural assembly times and protect platforms from mechanical damage.
Traditional wood formwork systems require mechanical anchors, which can damage expensive casting steel tables over time. Our shuttering magnet solutions (ranging from 600 kg to 2400 kg holding forces) provide non-destructive, reusable fixing points that reduce labor costs, speed up demolding cycles, and improve safety in precast production.
By using highly stable Y35, Y40, and customized NdFeB ring assemblies, we supply loudspeaker factories with motor configurations that maintain a consistent magnetic field across the voice coil gap, reducing total harmonic distortion (THD) and improving transient response.
Sintered NdFeB magnets are essential for direct-drive offshore wind generators and EV propulsion systems. Our thermal-stabilized UH and EH grade segments operate reliably under heavy cyclic loads, retaining over 95% of their magnetic output even after long runs at 180°C.
Every production run undergoes strict quality checks, including dimensional laser scans, hysteresis loop mapping, and salt spray testing. This ensures full compliance with international engineering guidelines.
In precast concrete production, shuttering molds shape edges and openings on flat surfaces using magnetic fixation. Understanding the structural differences between these assemblies is key to optimizing formwork configurations and improving production efficiency.

Read Full Press Release →Demagnetization occurs due to heat exceeding the Maximum Operating Temperature ($T_{max}$), chemical corrosion breaking down the matrix, or exposure to strong opposing magnetic fields. We prevent this by matching application temperatures with the correct grade series (H, SH, UH, EH, AH) and using multi-layer anti-corrosion platings like Ni-Cu-Ni or Epoxy.
Holding force calculations must account for the formwork profile height, structural concrete weight, vibration forces, and the friction coefficient of the steel bed. As a rule of thumb, high formwork profiles require higher magnetic holding forces (e.g., 2100 kg to 2400 kg systems) to prevent lateral shifting during concrete pouring and high-frequency vibration.
For standard sizes and grades, typical factory lead times range from 15 to 20 days. Custom configurations requiring specialized tooling, precise electrical discharge machining (EDM) cutting, or specific plating cycles generally take 25 to 35 days, including full quality testing and magnetic flux certification.
Yes, air freight shipping for magnets must comply with IATA packing instruction 953. This requires shielding the cargo so that the magnetic field strength does not exceed 0.00525 gauss at a distance of 4.6 meters from any point on the package. We offer specialized sheet-metal shielding packaging to ensure hassle-free customs clearance and safe shipping.
