Permanent Samarium Cobalt Block Magnet

Samarium Cobalt Block Permanent Magnet

Samarium Cobalt (SmCo) is considered the top choice for many high-performance applications as the first commercially viable rare earth permanent magnet material.

 

Developed in the 1960s, it revolutionized the industry by tripling the energy product of other available materials at the time. SmCo magnets have energy products ranging from 16MGOe to 33MGOe. Their exceptional resistance to demagnetization and excellent thermal stability make them ideal for demanding motor applications.

 

Compared to Nd-Fe-B magnets, SmCo magnets also boast significantly higher corrosion resistance, although coating is still recommended when exposed to acidic conditions. This corrosion resistance has made them popular in medical applications. Although SmCo magnets have magnetic properties similar to Neodymium Iron Boron magnets, their commercial success has been limited due to the higher cost and strategic value of Cobalt.

 

As a rare earth magnet, SmCo is an intermetallic compound of samarium (a rare earth metal) and cobalt (a transition metal). The production process involves milling, pressing, and sintering in an inert atmosphere. The magnets are then pressed using either an oil bath (iso statically) or a die (axially or diametrically).

Samarium cobalt magnet is mainly formed by the metal samarium, cobalt, and some other rare earth elements of the permanent magnet. lt has a high magnetic energy product, super low-temperature coefficient, and an operating temperature can up to 300℃. At the same time, it has strong corrosion resistance and oxidation resistance. Therefore, SmCo magnetic steel usually does not need to be electroplated and is widely used in motors, meters, sensors, engines, radar, and for other high-tech fields.

- Production: Powder metallurgy.
- Composition: SmCo5/Sm2C017
- Performance: High resistance demagnetization and good temperature physical properties and well resistance to corrosion.Excellent resistance to corrosion and oxidation
- Breakable
- Hardly to be demagnetized
- Lower temperature coefficient
- The proper working temperature is 100℃ to 350℃ but can also be used in bad condition
