Sintered NdFeB Magnets
Sintered Neodymium Iron Boron (NdFeB) is the most powerful permanent magnet available today, essential for high-efficiency motors, clean energy, and advanced electronics.
Why Partner With Us in the Current Market?
Amidst the tightening of global rare earth export controls, ensuring a resilient supply chain is critical. We offer a strategic advantage:
Heavy Rare Earth (HRE) Free Technology: By utilizing advanced grain boundary diffusion (GBD) and HRE-free processes, we provide high-coercivity magnets (up to $SH$, $UH$ grades) that minimize reliance on restricted heavy rare earths like Dysprosium ($Dy$) and Terbium ($Tb$).
Guaranteed Supply Stability: As a leading manufacturer, we maintain a robust strategic reserve of raw materials, ensuring your production line never stops.
Flexible MOQ & Customization: Whether you are in the R&D stage requiring small batches or scaling to mass production, our flexible Minimum Order Quantity (MOQ) supports your growth.
Fair & Real-Time Pricing
Guaranteed Material Integrity
Batch-to-Batch Consistency
Why Our Sintered NdFeB Stands Out
1. Exceptional Magnetic Consistency
Utilizing state-of-the-art vacuum induction melting and strip casting, we ensure a standard deviation of magnetic flux within $\pm1\%$ for high-precision applications.
2. Advanced Coating Technology
Our proprietary plating processes offer superior corrosion resistance, capable of passing 48-96 hours of salt spray testing (SST) even for small, complex geometries.
3. Deep Application Expertise
With 15 years in the industry, we specialize in high-temperature stability (up to $230^{\circ}C$ for $AH$ series) and complex magnetization patterns for EV motors and industrial automation.
We simplify the complex technical procurement of magnets into three professional stages:
1. Requirement & Technical Consultation
We don't just take orders; we consult. Our engineers work with you to define critical parameters: Grade ($N/M/H/SH/UH/EH/AH$), dimensions, tolerances, coating (NiCuNi, Zinc, Epoxy), and magnetic circuit design.
2. Prototyping & Rigorous Testing
Before mass production, we provide precision samples. Each prototype undergoes strict testing, including $Br$, $Hcb$, $Hcj$, and $(BH)_{max}$ verification, as well as salt spray and PCT/HAST tests if required.
3. Mass Production & Quality Assurance
Upon sample approval, we move to high-consistency mass production. Every batch is tracked via an ERP system and delivered with a full demagnetization curve report and dimensional inspection certificate.
FAQ for Sintered NdFeB Magnets
How do you ensure the stability of magnet performance at high temperatures?
We use high-coercivity grades and optimize the microstructure of the magnets. For applications above 150℃, we recommend EH or AH series. We can provide demagnetization curves at specific operating temperatures to verify thermal stability.
What is the lead time for custom NdFeB magnets under current export regulations?
For standard prototypes, it is usually 10-15 days. For mass production, it is typically 25-35 days. As we have optimized our export compliance and material sourcing, our lead times remain among the most competitive in the industry.
Can you help optimize the magnetic circuit to reduce costs?
Yes. Our technical team can analyze your assembly and suggest optimizations, such as adjusting the magnet grade or geometry, to achieve the required Gauss level while reducing the volume of material used.
Which coating is best for magnets used in humid environments?
For high-humidity or outdoor use, we recommend Black Epoxy or Everlube coating. For standard industrial use, high-quality Ni-Cu-Ni provides excellent protection and a professional metallic finish.
