Samarium magnets have high coercivity and high remanence due to their material. Therefore it has a high resistance to demagnetization. Thanks to their magnetic properties, they are perfect for small spaces where a high magnetic field is required.
The samarium magnet has a maximum energy of 15 MGo to 32 MGo
These magnets have a high energy density and are highly resistant to demagnetization. In addition, since they are made with rare earths, they can be worked between a temperature range of -40ºC to 350ºC.
Samarium magnets, together with neodymium magnets, are part of the rare earth group and represent the new generation of magnetic materials. Our high-quality samarium magnets are the second strongest material after neodymium but with higher working temperatures and higher coercivity.
Samarium magnets cost more than neodymium magnets because the raw material for cobalt (a key component in its manufacture) is produced abroad. However, the neodymium magnet has a greater resistance to high temperatures, so depending on the place of application and the temperature that is required, we will use the samarium magnet since the neodymium magnet does not have such a high working temperature.
Within samarium magnets, we can find two types: SmCo5 with a maximum working temperature of 750ºC, while Sm2Co7 can resist temperatures up to 850ºC.
Below you can find a table that lists the most important qualities and characteristics of samarium magnets. In the table, you will find variables such as the remanence of the magnets, the coercive force, the working temperatures, and the minimum and maximum resistance.
