FAQ
Q1. What considerations apply when exporting high-strength NdFeB magnets?
High Gauss magnets may require magnetic shielding and compliance testing to meet air and sea transport regulations. Packaging design, magnetization state, and shielding materials must be verified to ensure regulatory compliance and shipment safety.
Q2. How does aging affect NdFeB magnet performance over time?
When properly designed and operated within specifications, NdFeB magnets exhibit minimal magnetic aging. Performance degradation is usually linked to thermal stress, corrosion, or mechanical damage rather than natural aging of the material.
Q3. Can NdFeB magnets be optimized for reduced rare earth content?
Yes. Through grain boundary diffusion and optimized microstructure, high coercivity can be achieved with reduced heavy rare earth usage. This improves cost stability and supply chain sustainability without sacrificing performance.
Q4. Why Gauss Testing Matters?
Quality control: Confirms proper magnetization.
Incoming inspection: Verifies supplier consistency.
Application fit: Ensures sufficient holding force or sensor performance.
Troubleshooting: Identifies demagnetization or uneven magnetization.
