SmCo5 Rare Earth Permanent Magnets for aerospace, defense industry, microwave devices, communications, medical equipments, instruments, wind power, a variety of magnetic drives, sensors, magnetic processors, high-end motors…
Advantages of Samarium Cobalt SmCo5 Magnets
• Can be used in extremely cold conditions (e.g. to a few Kelvin above absolute zero).
• SmCo can be used up to +300 degrees C (572F); the H rated versions up to +350 degrees C (662F).
• High coercivity (Hci) to resist demagnetisation.
• Above +150 to +180 degrees C (302-356F) the SmCo starts to offer more performance than NdFeB grades.
• SmCo is regarded as being corrosion resistant.
• Very low field strength change with varying temperature.
Disadvantages of Samarium Cobalt Magnets
• Sm2Co17 should be given a protective coating when in very damp conditions to minimise any surface corrosion risk (Sm1Co5 does not rust as it contains no iron).
• Generally higher cost than NdFeB.
• All magnets are brittle but SmCo is the most brittle.
According to the different components of the SmCo5 and Sm2Co17, respectively, they are the first generation and the two generation rare earth permanent magnetic material. Because of its raw materials are scarce, the price is expensive and limit the development. Samarium cobalt (SmCo) as the second generation rare earth permanent magnet, not only has a high magnetic energy product (14-28MGOe) and reliable coercivity, and exhibits excellent temperature characteristics in rare earth permanent magnet series. Compared with the NdFeB, SmCo is more suitable for working in high temperature environment.Sm2Co17 (SmCo permanent magnets).

Rare Earth Permanent Magnets SmCo
SmCo Magnets
1)Constitution: 35% Sm, 60% Co and 5% Fe & Cu
2)SmCo Magnet(Samarium Cobalt magnet) has superior resistance to high temperature(max temp reaches 350 degree centigrade).When working at above 180 degree centigrade, its maximum energy product BH and temperature stability are superior than NdFeB magnet.
2)Excellent resistance to corrosion, no coating is needed for the surface protecting.
3)SmCo is suitable for machines with high magnetic requirements and good for strict working environment requirements
4)All sorts of SmCo are used in the electronic magnetron, magnetic transmission, magnetic treatment, magnistor, etc
5)Certification: ISO 9001 quality system
