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.

As part of the rare earth group of permanent magnets, samarium cobalt(SmCo) magnets have very high magnetic properties and temperature properties. Their Curie temperature can be as high as 710 to 880℃, maximum working temperature can be 250 to 350℃, so this kind of magnets have the best magnetic stability. They include rare earth Sm1Co5 and Sm2Co17 and are referred to as 1:5 and 2:17 materials. There’re three different manufacturing processes: sintered SmCo magnet, bonded SmCo magnet, and injection molding SmCo magnet.

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
