What are the uses of NdFeB permanent magnet materials?
one. NdFeB permanent magnet material is a strong magnetic material.
NdFeB is an intermetallic compound composed of three elements, neodymium, iron and boron, and is an excellent magnetic material. After magnetization, its magnetic properties are not only strong, but also can be maintained for a long time, which is an excellent permanent magnet material.
The basic characteristic parameters of permanent magnet materials are as follows:
1. Remanence Br unit Gauss (Gs )
2. Coercivity Hcb and Hcj, unit Oersted (Oe)
3. Magnetic energy product (BH)max,
4. Curie temperature TC, unit ℃.
5. Use temperature (temperature coefficient).
two. NdFeB permanent magnet material is a good material for magnetic and medium price
The current production and application are barium ferrite, strontium ferrite: cheap products.
Alnico: Dominant in pointer gauges.
Samarium Cobalt: Predominant in military and consumer goods.
Platinum Cobalt: Mainly used in aircraft black boxes, with very few products.
NdFeB: It has dominated the electronic computer and its peripheral equipment, and its applications in other aspects are becoming more and more extensive.
NdFeB permanent magnet material has strong magnetism, medium price, and good stability under the protection of surface coating, so it has a good development trend of expanding its use range.
