Precision Ni-Cu-Ni Coated Industrial NdFeB Cylinder Magnets

100% Virgin Rare Earth Materials (No Recycled Content)

We guarantee that all Sintered NdFeB Cylinders are manufactured using 100% virgin rare earth formulations. No recycled materials are added at any stage. This ensures stable magnetic performance over time without abnormal degradation, maintaining the intrinsic purity of high-grade rare earth magnets.

2. Zero Tolerance for Dimensional Deviation

In precision industrial applications, even the smallest deviation can lead to system failure. Our Precision Industrial Magnets strictly reject any out-of-tolerance products. Standard dimensional tolerance is tightly controlled within ±0.05 mm, ensuring seamless integration into automated production lines without feeding issues or assembly interference.

3. Strict Control of Coating Quality (No Compromise on Plating)

We do not accept misleading salt spray test claims or substandard coatings. Our Ni-Cu-Ni plated magnets are produced using a true triple-layer electroplating process, not single-layer shortcuts. This ensures no peeling, flaking, or rusting under humid or harsh environments, significantly reducing downstream after-sales risks for end products.

4. No Rough Edges or Chipping (Precision Edge Finishing)

Although magnets are inherently brittle, quality must not be compromised. We strictly reject any permanent cylindrical magnets with cracks or severe edge chipping. Through precision chamfering and fine grinding processes, every cylinder is finished with smooth edges, preventing magnetic powder shedding and protecting customers’ sensitive electronic components from contamination.

Flawless Appearance

Precisely chamfered with smooth edges and no chipping, reducing magnetic powder shedding during use and improving overall product durability.

• Superior Zinc Coating

Environmentally friendly zinc coating designed for industrial applications:

• Corrosion Resistance
  Passed 24–96 hours Salt Spray Test (SST), effectively preventing oxidation in dry or indoor environments.

• Cost-Effective Solution
  Compared with NiCuNi coating, zinc coating provides reliable basic corrosion protection with moderate coating thickness while significantly reducing procurement costs.

Excellent Magnetic Performance Stability

Manufactured with high-purity rare earth raw materials to ensure the demagnetization curve meets industry standards.

• Consistency
  Each production batch undergoes magnetic declination testing and magnetic flux spot inspection to ensure surface magnetic variation is controlled within 5%.
