About Neodymium-Iron-Boron Magnet:
- The NdFeB magnet is the strongest permanent magnet in the world.
- It is a tetragonal crystal formed of neodymium, iron, and boron.
- It is made mainly from a combination of Neodymium, Iron, Boron, Cobalt and varying levels of Dysprosium and Praseodymium.
- Neodymium Magnets can be divided into three types:
- Sintered NdFeB magnets: It has the largest output and the most widely used in the NdFeB family.
- Bonded NdFeB magnets: This has the advantages of low cost, high dimensional accuracy, a large degree of freedom of shape, good mechanical strength, and has been widely used in the market.
- Hot-pressed NdFeB magnets: They can achieve magnetic properties similar to sintered NdFeB without adding heavy rare earth elements.
- They have the advantages of high density, , and high coercivity, but the mechanical properties are not good. high orientation, good corrosion resistance.
- Due to different production processes, they have big differences in product magnetic properties, post-processing, and applications.
- Applications: It is widely used in electronic products, such as hard drives, mobile phones, earphones, and battery-powered tools.
