Detailed Samarium Cobalt - SmCo Magnet Description
Features:
a) Rare earth magnet with a high percentage of samarium, which is
relatively stable against temperature change
b) With high energy product and excellent coercive force, this material is
ideally compact and suitable to highly efficient machines and
components
c) Widely used in applications in which higher operation temperature,
higher corrosion and oxidation resistance are crucial
d) Two common compositions: Sm1Co5 and
Sm2Co17
e) High energy ranging from 14MGOe to 30MGOe
f) Reliable coercive force
g) With the best temperature characteristics in rare earth material
family
h) Compared to NdFeB, SmCo is suitable for higher temperature than
200oC and has greater magnetic output at temperatures
above 150oC
i) Less subject to corrosion and usually does not require surface
protection
j) Due to high brittleness and powerful magnetic force of Samarium
Cobalt product, it must be handled with special care
k) Advantages for using SmCo:
1) Extremely high magnetic properties
2) Outstanding thermal stability
3) Excellent corrosion resistance
l) Disadvantages:
1) Most expensive
2) High brittleness
m) SmCo is the ideal material in applications such as pump couplings,
sensors, servo - motors, particularly where the magnet is required to
service at elevated temperatures, across a broad temperature range
or in a corrosive environment
