Neodymium magnets (NdFeB), the most powerful permanent magnets commercially available, are classified by their maximum energy product (BH)max, which correlates to their magnetic flux output per unit volume. As a premier wholesale Neodymium Magnets manufacturer, QCM Magnet provides an extensive spectrum of grades ranging from N35 for cost-effective packaging solutions to N52H for high-intensity industrial applications.

The "N" in the grade refers to Neodymium, and the following number (e.g., 35, 42, 52) represents the magnetic strength. However, for industrial procurement, the suffixes are equally critical. We offer specialized thermal stability suffixes:
At QCM Magnet, we don't just supply magnets; we engineer magnetic fixing solutions that redefine construction efficiency. The precast concrete industry has undergone a paradigm shift, moving from traditional welding and bolting to reusable magnetic formwork systems. This transition, fueled by high-grade NdFeB magnets, has reduced labor costs by up to 40% and extended the lifespan of steel casting platforms.
Our Shuttering Magnets (ranging from 600kg to 2500kg pulling force) utilize a sophisticated magnetic circuit design. By encasing N52 neodymium magnets within a carbon steel or stainless steel housing, we amplify the vertical pull force while protecting the brittle rare-earth material from the harsh, alkaline environment of concrete production. This synergy of material science and mechanical engineering is what sets QCM apart as a global leader.
The demand for smaller, more powerful magnets is peaking in the electronics and medical device sectors. We are now producing N55 grades to meet these micro-scale requirements.
Modern manufacturing focuses on reducing Dysprosium (Dy) and Terbium (Tb) content while maintaining high coercivity through grain boundary diffusion (GBD) technology.
Magnetic sensors and automated formwork systems are integrating with IoT, requiring magnets with extremely tight tolerances and magnetic consistency.
Procuring neodymium magnets at scale requires a partner who understands the complexities of international trade and material compliance. QCM Magnet is fully certified under ISO 9001:2015 and CE standards, ensuring that every batch meets rigorous safety and performance benchmarks.
All coatings—whether Ni-Cu-Ni, Zinc, or Epoxy—are tested for environmental safety and corrosion resistance (SST up to 96 hours).
We maintain deep relationships with rare-earth mines to stabilize pricing for our wholesale partners, shielding them from market volatility.
With participation in events like UK Construction Week 2025, we provide localized technical consulting and rapid prototyping for European and American markets.
Looking toward 2030, QCM Magnet is investing in three core areas of magnetic innovation:
N35 is a standard entry-level grade with a Maximum Energy Product of 33-36 MGOe, whereas N52 is the highest commercial strength (50-52 MGOe). N52 provides approximately 20% more magnetic pull for the same volume, allowing for more compact designs.
It depends on the height and weight of your side form. For standard 100-150mm slabs, a 1000kg (2200 lbs) magnet is usually sufficient. For heavier structural walls, we recommend our 2100kg or 2500kg models to ensure zero slippage during vibration.
Standard N-grade magnets lose magnetism permanently above 80°C. If your application involves heat, you must specify H, SH, or UH grades. Our "AH" series can withstand up to 230°C.
We provide full OEM/ODM services, including magnetic circuit simulation (FEA), custom housing fabrication, and specialized coating applications to meet unique industrial requirements.
