About Samarium Cobalt magnets

• Samarium Cobalt magnets or SmCo are strong
  permanent magnets made of an alloy of samarium
  and cobalt. It is less subject to corrosion than
  a Neodymium magnet, and usually does not require
  coating or plating. Suitable for certain
  applications than Neodymium magnets, these are
  known for high magnetic strength, exceptional
  temperature resistance and reliable performance
  without oxidation protection. This magnet can
  withstand higher temperatures than a Neodymium
  magnet. The maximum operating temperatures of
  Samarium Cobalt magnet is between 250 and 550 C,
  Curie temperatures range from 700 to 800 C.
  Having to design around this temperature range
  leads to large performance differences in the
  magnet properties. In other words, a machine
  operating at room temperature will have more
  torque than a machine operating at 180C for the
  same amount of input current.

• 15 offers 16 MGOe to 22 MGOe and is made up of
  approximately 50 samarium and 50 cobalt. The
  15 series has a recommended operating
  temperature of 250C and requires lower field
  strengths than 217 materials to magnetize.

4

• The 217 series has a maximum operating
  temperature of 350C. 217 offers 24 MGOe to 32
  MGOe, composed of about 25 samarium, 5 copper,
  18 iron, 2 hafnium or zirconium, with the
  remainder being cobalt.

• The magnetic fields produced of Samarium Cobalt
  magnets ranges from 0.8 to 1.15 Tesla. It is by
  far the best product when power and high
  temperature resistance is required.

6

• It can operate in conditions up to 500C without
  suffering any magnetization loss. Magnetization
  integrity is high in these magnets, as they
  resist demagnetization handily.

7

• Special grades of 217 can operate to even higher
  temperatures and requires a higher magnetizing
  field than alloy 15 does and multiple pole
  magnetization is sometimes possible.
