Samarium Cobalt

We are not only a magnetic products manufacturer but also a realizer of your
ideas. After fully understanding all of the requirements of our customers, we
will carry out the following program verification and magnetic separator
product production links.

As a professional samarium cobalt magnet manufacturer, Leyuan would like to
introduce you samarium cobalt rare earth permanent magnets which come in energy
products from 16MGOe up to 33MGOe. Their high resistance to demagnetizing
influences and excellent thermal stability has ensured Sm-Co as the premium
choice for the most demanding motor applications. In addition to this, the
corrosion resistance is significantly higher than, for example, Nd-Fe-B. It is
still recommended to coat the magnet in acidic conditions. Its corrosion
resistance has also offered a high degree of comfort to those looking to use
magnets in medical applications.

Its magnetic properties are not too far from Neodymium Iron Boron magnets but,
due to the  cost and strategic value of Cobalt, it never had the commercial
success and diffusion of NdFeB. Being a most powerful neodymium magnet, it is
an intermetallic compound of rare earth metals (samarium) and transition metals
(cobalt). The production process consists in milling, pressing, and sintering
in an inert atmosphere: magnets are then pressed in an oil bath (isostatically)
or in a dye (axially or diametrically). SmCo is processed by grinding with
diamond tools. As mentioned, SmCo can provide high magnetic performances, with
maximum energy production of around 240 KJ/m3: they can be found in two
different grades, Sm1Co5 and Sm2Co17, and each one has its own specific
magnetic behavior (nucleation for the first, pinning in Sm2Co17). Sm2Co17 shows
the highest magnetic performances but, on the opposite side, it is much more
difficult to be magnetized (4000 kA/m) than Sm1Co5 (2000 kA/m). The two
advantages of smco magnet grades versus NdFeB are the corrosion resistance and
the good thermal behavior; Curie temperature is around 750°C for Sm1Co5 and
850°C for Sm2Co17 . Furthermore, the rate of magnetic properties decrease is
rather low by increasing the temperature. Samarium cobalt magnet grades are
best appreciated in military and aerospace industries, as well as in the
electromedical field; they should be preferred when oxidation or thermal needs
become very important. Its industrial applications are similar to the ones of
NdFeB: sensors, loudspeakers, electric motors, instruments, and switches.

As one of the most professional smco magnet manufacturers from China, Leyuan
has the samarium cobalt ring magnets for sale. If you want to know samarium
cobalt magnet price, please contact Leyuan or leave a message through our
website.
