| titleOfInvention | Neodymium-iron-boron material and preparation method and application thereof |
| abstract | The invention discloses a neodymium iron boron material and a preparation method and application thereof. The raw material composition of the neodymium iron boron material comprises the following components in percentage by mass: r: 28.5 to 33.0 percent; r is a rare earth element at least containing Nd; cu: 0.45-2% but not 0.45%; b: 0.84-0.94%; al: 0.05-0.07%; co: less than or equal to 2.5 percent but not 0; fe: 62-70%; n: one or more of Ti, Zr and Nb; when N contains Ti, the content of Ti is 0.15-0.25%; when N contains Zr, the content of Zr is 0.2-0.35%; when the N contains Nb, the content of Nb is 0.2-0.5%; the percentage is the mass percentage of each component in the total mass of the raw material composition. The neodymium iron boron material has better magnetic property, and the magnetic property of products in the same batch is uniform. |
