Advantage

Samarium magnets are magnetic elements obtained by the combination of raw materials such as samarium and cobalt that belong to the group of rare earths, with excellent behavior against corrosion and oxidation. It also maintains a stability to the magnetic curve thanks to the high temperature of Curie. It is a material with very positive coercive values, a factor that favors the resistance to demagnetization, together with the high resistance to high temperatures (up to 350ºC) make these magnets indispensable for certain applications.

It is a material with very positive coercive values, a factor that favors the resistance to demagnetization, together with the high resistance to high temperatures (up to 350ºC) make these magnets indispensable for certain applications.

Work temperature

The working temperature can condition the use of these samarium magnets, which work up to 350ºC, without presenting problems with oxidation. It also has the peculiarity of being used in temperatures below 0ºC.

Applications

The scope of use of samarium magnets is very similar to that of Neodymium, obtaining a large number of applications. The ability to work at high temperatures and high energy values, provide different uses such as sensors inside furnaces, detectors in boilers, accessories in electric motors or simply for needs that require thermal stability. A totally suitable material and recommended for the industrial sector.

Production process

To use permanent samarium magnets a series of precautions are necessary as they can cause injuries if they are not used correctly.

  1. The raw material is exposed to high temperature, to melt it and create the desired alloy.
  2. The alloy is poured into a mold and cooled until solid pieces are obtained.
  3. The pieces are then broken and molded into tiny particles.
  4. Finally, it is coated and magnetized by an external magnetic field to verify its quality.
