  • How do NdFeB magnets differ from other magnet types?

    1. NdFeB magnets are known for their exceptional magnetic strength, surpassing other magnet types such as SmCo or ceramic magnets. They also offer a high energy product, allowing for smaller and more compact designs. However, NdFeB magnets are more susceptible to corrosion and have lower temperature stability compared to SmCo magnets

  • Are there different grades of NdFeB magnets?

    Yes, NdFeB magnets are available in various grades, such as N35, N42, N52, etc. The grade indicates the maximum energy product of the magnet material. Higher-grade magnets have greater magnetic strength but may have lower temperature stability. The choice of grade depends on the specific application requirements.

  • What is SmCo?

    1. SmCo stands for Samarium Cobalt, which refers to a type of permanent magnet material. SmCo magnets are composed of a combination of the rare-earth element samarium (Sm) and the transition metal cobalt (Co).

  • How do SmCo magnets differ from other magnet types?

    SmCo magnets differ from other magnet types, such as neodymium magnets, in terms of their higher temperature stability and resistance to demagnetization at high temperatures. SmCo magnets also have higher magnetic strengths in some cases, but they are more brittle and expensive compared to neodymium magnets.
