• 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.
