Customized Permanent NdFeB Magnent Adavantage

1. Strong power magnet
2. Higher unit magnetic properties
3. Higher energy
5. High Hc and Hci output
6. Mostly an iron based alloy, NdFeB type rare earth magnet is much more prone to surface oxidation or rust,
Users should consider magnet coating, plating or suitable surface treatment
7. Less prone to chipping during handling
5. Lower temperature coefficient of magnetic properties than ceramic, higher than SmCo type rare earth magnet
6. More economical than SmCo
