SmCo Series 1:5
SmCo Series 1:5 has one atom of rare earth samarium and five atoms
of cobalt. By weight this magnet alloy will typically contain 36%
samarium with the balance cobalt. SmCo magnets generally have a
reversible temperature coefficient of -0.05%. The maximum working
temperature is about 350 ℃.
SmCo Series 2:17
SmCo Series 2:17 are age-hardened with a composition of two atoms
of rare-earth samarium and 13-17 atoms of transition metals(TM).
The TM content is rich in cobalt, but contains other elements such
as iron and copper.
Other elements like zirconium, hafnium, and such may be added in
small quantities to achieve better heat treatment. By weight, the
alloy
will generally contain 25% of samarium. The maximum energy of these
alloys ranges from 24 to 30 MGOe. SmCo magnets generally have
a reversible temperature coefficient of -0.03% ℃. The maximum
working temprature is 350℃
