Samarium Cobalt (SmCo) Magnets
Extremely strong rare earth magnets, Samarium Cobalt magnets (SmCo) are composed of samarium, cobalt and iron. Not sure if samarium cobalt is the best material for your application? Review our permanent magnetic materials comparison for more information.

Manufacturing – In general, the elements are melted together and milled into a powder that is dry-pressed to shape in the presence of a magnetic field. The material is then sintered, aged, ground to dimension, magnetized and tested. They are called “rare earth” magnets because the elements of samarium cobalt are classified as such in the lanthanides section of the Periodic Table of the Elements.

YXG-26M Customer SmCo Magnetic Rings for Motor

Samarium cobalt magnet mainly has two compositions, i.e. SmCo5 and Sm2Co17, and is a magnetic material made by matching samarium, cobalt and other metal rare earth materials, smelting into alloy, smashing, pressing and sintering. It has high magnetic energy product and low temperature coefficient. Its maximum working temperature can reach 350ºC, its negative temperature is unlimited, and when the working temperature is above 180ºC, its temperature stability and chemical stability exceed those of Nd-Fe-B permanent magnet material.

Applications of Samarium Cobalt Magnets
Computer disc drives
Sensors
Traveling wave tubes
Linear actuators
Satellite systems
Motors where temporary stability is vita
Servo-Motors
Transducers
Watch
Positional detector
Generators

Attributes of Samarium Cobalt Material
High resistance to demagnetization
High energy (magnetic strength is strong for its size)
Good temperature stability
Expensive material (cobalt is market price sensitive)
Excellent corrosion resistance

DISC MAGNET:
General size range: D: 1 – 120mm, H: 0.5 – 150mm
Max disc: D160 × H60mm(Large D/H ratio), D60 × H150mm(Large H/D ratio)
Min disc: D1 × H0.5mm
Note: For large discs, too thin thickness is not allowed, because the great brittleness of SmCo easily causes fracture when assembling. Please contact technical support for details. Customized Special Arc Heat Resistant Samarium Cobalt Magnet for Industry
