This group is formed by the magnets Samarium Cobalt (SmCo5 and Sm2Co17). Their main elements, the so-called Rare Earth Sm and Nd, belong to the lanthanide metal series of the periodic system of elements.
General Information: SmCo magnets are manufactured by sintering process. They are anisotropic and can only be magnetized in the direction of orientation. In general, magnetizing fields of approximately 30 to 45KOe are required to saturate SmCo magnets.
These magnets possess very high magnetic properties, excellent thermal stability, while remaining resistant to corrosion. These characteristics make SmCo magnets ideal for applications requiring a resistance to wide-ranging temperatures and rough environments. They provide high stability, but cause higher prices as well.
Temperature Effects: SmCo magnets have an operating temperature of up to 300-350°C, depending on the grade and permeance coefficient.
Applications: Charged particle beam guidance, headphones, holding systems, instruments, loudspeakers, magnetic bearings, magnetic couplings, magnetic resonance, magnetic separations, microphones, particle accelerators, relays, switches, as well as many other applications.
