NdFeB Magnets - Neodymium Iron Boron magnets
|
 |
Material Information
|
- Produced by powder metallurgical method with chemical composition of Nd2Fe14B
- High resistance to demangnetization
- High magnetic values (Br, bHc, iHC und (BH)max)
- Excellent cost to performance ratio
- Reasonable temperature stability
- Very brittle & hard
- Poorest corrosion resistance of all commercial magnetic materials
- Not suitable for application which exposed in high temperture conditions
