Our HRE free magnets( (Zero-Dysprosium/Terbium) achieve industry-leading magnetic properties across the N, M, H, and SH series, reaching up to N54 and N48SH. They offer performance parity with traditional grades while ensuring a more stable supply chain and a streamlined, predictable international distribution process.
Magnetic Separators: N54 magnets provide maximum surface gauss for capturing micro-sized contaminants in fine powders.
EV & Servo Motors: N48SH and N52H grades ensure high thermal stability and precision for automotive and robotic drivetrains.
Consumer Electronics: N54 series deliver peak energy density for high-fidelity acoustics and advanced haptic feedback.
Wind Power: Sustainable, heavy-rare-earth-free solutions for stable, large-scale permanent magnet generators.
In the rare earth magnet industry, HRE (Heavy Rare Earths) or HREE (Heavy Rare Earth Elements) typically refers to elements such as Dysprosium (Dy) and Terbium (Tb). These elements are traditionally used to enhance the heat resistance of NdFeB magnets.
Our HRE Free Magnets utilize a breakthrough metallurgical approach to eliminate Dy and Tb entirely. By optimizing the base alloy and grain structure, we provide a Zero-Dysprosium solution that offers superior magnetic properties and enhanced predictability for your global logistics.
We offer a comprehensive portfolio of Dy-free NdFeB magnets that match the magnetic specifications of traditional grades, ensuring a seamless transition for your engineering requirements.
The N54 HRE Free grade represents the peak of magnetic flux density. Since it contains no heavy rare earths to suppress induction, it achieves higher remanence ($B_r$) than traditional alternatives.
Designed for medium-to-high temperature environments (up to 120°C), our N52H HRE Free magnets provide a stable Hcj ：16-17 kOe. These are ideal for high-speed rotors and precision actuators.
Our N48SH HRE Free magnets reach the SH thermal rating (up to 150°C) without the use of Heavy Rare Earths. Unlike many products on the market, these do not rely on Grain Boundary Diffusion (GBD), ensuring uniform magnetic performance throughout the entire magnet volume.
While the specialized sintering and high-purity raw materials required for high-Hcj HRE Free magnets may lead to a higher production cost, the long-term strategic benefits are significant:
Supply Chain Resilience: Decouple your production from the volatile pricing and availability of Dysprosium and Terbium.
Efficient Global Distribution: As these magnets are categorized as non-restricted high-performance materials, they offer a much more predictable and streamlined international delivery process compared to traditional HRE-based magnets.
Enhanced Magnetic Induction: The absence of HRE elements allows for a more optimized magnetic alignment, often resulting in superior Br values.
Uniformity & Reliability: Our Non-GBD manufacturing process guarantees that every part of the magnet—from surface to core—exhibits consistent coercivity.
Our HRE Free Neodymium Magnets are powering critical technologies worldwide:
Engineered for high-gradient magnetic separation systems, our N54 HRE-free magnets provide the extreme surface gauss required to capture micro-sized ferrous contaminants in fine chemical and food-grade powders. The high remanence ($B_r$) ensures maximum extraction efficiency, while the HRE-free composition allows for rapid international deployment for equipment manufacturers.
Optimized for traction motors and auxiliary systems requiring N48SH grade thermal stability. Our HRE-free technology ensures reliable torque and efficiency while providing a more predictable supply chain for global automotive OEMs.
Perfect for high-speed rotors in precision robotics. With grades up to N52M and N50H, these magnets deliver consistent magnetic flux and high coercivity, matching the performance of traditional heavy-rare-earth magnets without the logistical complexities.
The N54 HRE-free grade offers peak energy products for premium speakers, headphones, and haptic feedback motors. Removing heavy rare earths results in higher remanence ($B_r$), delivering superior sound pressure and vibration sensitivity.
Provides a sustainable and stable material platform for large-scale permanent magnet generators. By eliminating Dysprosium and Terbium, we offer long-term price stability and a simplified logistics path for green energy infrastructure projects.
Q: If the performance is the same, why is the cost higher? A: Achieving high coercivity without HREE requires ultra-pure raw materials and precise grain-size control during sintering (Non-GBD). This investment ensures you have a product that is fully compliant for export, shielding you from potential trade sanctions or HRE supply shortages.
Q: Can these replace my current N52H or N48SH magnets? A: Yes. Our N52H HRE Free and N48SH HRE Free are designed as “drop-in” replacements with identical dimensions and magnetic properties, making the transition seamless for your engineering team.
