NdFeB Magnets – Neodymium Iron Boron magnets
- Produced by powder metallurgical method with chemical composition of Nd2Fe14B
- High resistance to demagnetization
- High magnetic values (Br, bHc, iHC and (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 temperature conditioans
