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.
Material: Sintered SmCo
Grade: SmCo26,SmCo28, SmCo30, SmCo32
Dimensions: Per Drawing
Tolerance: +/-0.13
Coating: N/M
Magnetized direction.
Applications of Samarium Cobalt Magnets

Motors where temporary stability is vita
Servo-Motors
Transducers
Watch
Positional detector
Generators
Sintering SmCo Generator Permanent Segment Magnets
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
LOAF MAGNET:
General size range: W: 2 – 200mm, H: 1 – 200mm, L: 1 – 200mm
Max Loaf: W200 × H80 × L100mm(Large W/L ratio), W100 × H40 × L200mm(Large L/W ratio)
Min Loaf: W2 × H2 × L1mm
Note: For large loaf, any thin dimension is not allowed, because the great brittleness of SmCo easily causes fracture when assembling. Please contact technical support for details. Bullet Shape Permanent Rare Earth SmCo High Energy Magnets
SEGMENT MAGNET:
General size range: W: 3 – 200mm, H: 1 – 80mm, L: 2 – 200mm
Max Segment: W200 × H80 × L100mm(Large W/L ratio), W100 × H80 × L200mm(Large L/W ratio)
Min Segment: W3 × H1 × L2mm
Note: For large segment, any thin dimension is not allowed, because the great brittleness of SmCo easily causes fracture when assembling. Please contact technical support for details.
