Our current stacked magnets are mainly made of NdFeB, ferrite and SmCo magnets.
Compared to other permanent magnets, ferrite magnets have weaker magnetic force, but they are inexpensive. Ferrite stack can provide higher potential performance and control the cost as well. Therefore, many customers choose this material. But they can’t used on high precision application because of the machining accuracy of ferrite magnet.
Neodymium magnets are the strongest permanent magnets in the world. The magnets are small, high energy, and have high machining accuracy, so they are usually used in applications where super strong magnetic force and precise size are required.
Samarium cobalt magnets have high-temperature performance and temperature stability that sintered NdFeB magnets can’t compare. They usually used on industrial high temperature devices.
The selection of the correct permanent magnet material and grade is critical in the design of any magnetic product. A number of key parameters should be carefully considered when evaluating the correct material selection for your application. For example, maximum operating temperature, maximum energy product, and inherent coercivity (resistance to demagnetization). Read more or contact us to learn more about material selection.
