Short Description:

SmCo magnets represent the latest generation of magnetic materials. They are developed over 40 years ago and introduced the era of permanent magnet motors. At that time, these rare earth metals were very expensive. During the 1980s, SmCo material was increasingly replaced by NdFeB magnets. Due to the dramatic price rise in the rare earths neodymium and dysprosium (Nd/Dy), this material has now regained its popularity in applications at higher temperatures (150°C –  200°C). However, there are limits set on the material with regard to the maximum remanence.  Two major types of SmCo magnets are available, 1:5 type (SmCo5) and 2:17 type (Sm2Co17). SmCo magnets have super high magnetic properties and temperature properties.
