Samarium Cobalt magnet is a kind of permanent magnet which is composed by specific ratio of samarium, cobalt and other metallic materials. Its main characteristics are good magnet performance and high temperature resistance (250ºC-350ºC). It also has high magnetic energy and high coercivity. Compared with the NdFeB magnet, SmCo is more suitable for working in high temperature environment. It has good corrosion resistance, generally, no coating.

1. Application:
motors, loudspeakers, sensors, actuators, travelling wave tube, etc.
2. Material: 
SmCo Series 1:5
This kind of magnet alloys have one atom of rare earth samarium and five atoms of cobalt. By weight this magnet alloy will typically contain 36% samarium with the balance cobalt. The energy products of these samarium-cobalt alloys range from 16 MGOe to 25 MGOe, what is approx. 128 kJ/m3 - 200 kJ/m3. These samarium-cobalt magnets generally have a reversible temperature coefficient of -0.05%/°C. Saturation magnetization can be achieved with a moderate magnetizing field. This series of magnet is easier to calibrate to a specific magnetic field than the SmCo 2:17 series magnets.

SmCo Series 2:17
This kind of magnet alloys are age-hardened with a composition of two atoms of rare-earth samarium and 13-17 atoms of transition metals (TM). The TM content is rich in cobalt, but contains other elements such as iron and copper. Other elements like zirconium, hafnium, and such may be added in small quantities to achieve better heat treatment response. By weight, the alloy will generally contain 25% of samarium. The maximum energy products of these alloys range from 20 to 32 MGOe, what is about 160-260 kJ/m3. These alloys have the best reversible temperature coefficient of all rare-earth alloys, typically being -0.03%/°C. The "second generation" materials can also be used at higher temperatures.
