Uniform Magnetization & Structured Arrangement: Magnets are uniformly magnetized and arranged for optimal packaging based on customer requirements to ensure performance and facilitate automated assembly.

Vacuum Sealed Packaging: Multi-layer vacuum sealing with moisture barriers, desiccants or nitrogen, prevents corrosion and magnetic interference during storage and shipping.

Customized Outer Packaging: Shock-proof, moisture-resistant, and anti-magnetic leakage packaging (e.g., multilayer cartons, plastic boxes, metal shielding) ensures compliance with international logistics standards. Each box includes a product list, labels, and tracking codes.

7. FAQ

Q: How to choose the correct magnetization direction?

Axial Magnetization: Magnetic lines flow through thickness — best for concentrated fields

Radial Magnetization: Magnetic lines radiate outward — for uniform field distribution

Multipole Magnetization: Multiple poles along circumference — for complex fields (e.g., motors, sensors)

Q: What is the maximum working temperature of a ring magnet?

Standard N-series: up to 80°C

High-temp grades (SH/UH/EH): up to 150°C–230°C

Dysprosium-enriched formulations can further enhance temperature resistance

Q: Does magnetism decay over time?
Under normal conditions (room temp, dry, no heavy vibration), NdFeB magnets exhibit excellent time stability (<5% loss over 10 years). However, factors like:

Temperature overrun

Strong external magnetic fields

Surface corrosion

Mechanical impact may affect performance.
