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 a high hardness and should be manipulated only with tools that incorporate diamond, to cut or modify the magnet.

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.


ico-titleAPPLICATIONS:

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.


ico-titlePRODUCTION PROCESS:

Like any magnet, you must first follow some production phases, before obtaining the magnetic material prepared for your application..

In the first instance, the raw material is heated in an oven by induction and melted to obtain the material for the alloy.

Then, the alloy in a liquid state is poured into a mold and cooled by water, to obtain solid pieces, to subsequently break the pieces and grind them to obtain tiny particles..

As an option parallel to sintering, the powder obtained is combined with a chemical substance, pressed and heated while applying a magnetic field to orient the set of particles.

To conclude, if required, a coating will be applied and magnetized by an external magnetic field, being tested and verifying the quality of the product.
