SmCo is also named with SmCo
magnetic steel, SmCo
permanent magnet, SmCo
permanent magnetic iron and
rare-earth cobalt permanent
magnet. It’s a high
performance, low temperature
coefficient permanent magnet
with its high working
temperature—350 degree
centigrade. When working
above 180 degree centigrade,
its maximum energy product
BH and steady temperature
are superior than NdFeB
magnetic materials. It
needn’t to be coated because
it is
difficult to be eroded and
oxidized. SmCo magnet is
widely used in motors,
watch, transducers,
instruments, positional
detector, generators, radar
communications, medical
equipments, various
magnetism spreading devices,
magnetic processor,
electrical
engineering and magnetic
derrick,Samarium
Cobalt holds its standard
property in higher maximum
temperatures than
Neodymium,although
its maximum strength is
less. The cost of SmCo
material is the most
expensive,so SmCo is
recommended only when its
performance is a high
temperature environment is a
concern.
The characteristics of
Samarium Cobalt Magnet
*Very high magnetic
properties with good
stability.
*Superior resistance to high
temperature, Curie
temperature of majority is
over 800℃
*Excellent corrosion
resistance capability, no
coating is needed for
surface protection
