Large Size Sintered Ndfeb Permanent Magnet Ring
The Large Size Sintered NdFeB Permanent Magnet Ring from Zhejiang Chuangci Science & Development Co., Ltd is engineered as the largest sintered ring magnet available globally, with a maximum outer diameter of 300 mm and a minimum inner diameter of 60 mm. It delivers ultra-high magnetic field strength through magnet field rotation scanning, supporting both multi-pole and uni-pole OD/ID magnetization configurations. The ring achieves a working temperature threshold of 200°C, making it suitable for high-precision industrial and instrumentation applications.
Composed of neodymium, iron, boron, and trace metals, this sintered NdFeB magnet offers a maximum magnetic energy product (Bhmax) of 8-55 MGOe, with coercivity that exceeds ferrite magnets by a factor of ten. The material undergoes strict quality control during production, allowing for custom shaping, drilling, and surface treatments such as zinc, nickel, gold, or epoxy plating to mitigate corrosion risks inherent to its composition. Typical industry applications include motors, generators, medical imaging devices, and aerospace systems where compact, high-strength magnetic performance is critical.
This magnet ring is designed for OEM customization, catering to buyers in industries requiring large-scale, high-precision magnetic components. Its mechanical properties enable precise machining for tailored dimensions, while its thermal stability ensures reliable performance in demanding environments. Buyers typically source these rings for integration into specialized equipment, with lead times and packaging configurations confirmed directly with the supplier based on project specifications.

Sourcing Large Size Sintered Ndfeb Permanent Magnet Ring from Zhejiang Chuangci Science & Development Co., Ltd - China Import Guide
Before ordering, verify the exact dimensions, magnetization configuration, and surface treatment requirements with Zhejiang Chuangci Science & Development Co., Ltd to ensure compatibility with your equipment. Confirm whether the supplier can provide certificates of compliance for material composition and magnetic properties, as these are critical for quality assurance in industrial applications. Request samples for testing under your specific operating conditions to validate performance.
Discuss logistics details such as packaging, labeling, and shipping methods to prevent damage during transit, as sintered NdFeB magnets are brittle and sensitive to mechanical stress. Clarify lead times, which may vary based on customization requirements, and agree on Incoterms such as FOB or CIF to define responsibilities for shipping, insurance, and duties. Payment terms should also be negotiated upfront to align with your procurement policies.
Conduct quality checks upon receipt, including measurements of magnetic properties like residual flux density and coercivity using calibrated equipment. Inspect the surface treatment for uniformity and adherence to prevent corrosion. Ensure all documentation, including material test reports and compliance certificates, is provided and matches the agreed specifications. If third-party inspection is required, arrange it prior to shipment to avoid delays.
