There are several types of magnets that are referred to as Rare Earth magnets and Samarium Cobalt magnets one of these. They have several key attributes that make them well suited to particular applications. Automotive, marine and some medical applications utilise Samarium Cobalt magnets like this ring magnet as they have superior resistance to corrosive elements. In addition to this they are stable at high temperatures, continuing to provide sustained magnetic power at over 200 degrees Celsius. To find out more please take a look at our magnet wiki page.

Similar to other Rare Earth magnets, like Neodymium magnets, Samarium Cobalt magnets are quite brittle in nature. This is due to the sintering process that occurs in manufacturing the magnets. It is important to handle all magnets with care as they can chip or shatter when subjected to impact. This is particularly the case with Samarium Cobalt ring magnets. The thin profile and central hole mean they are more likely to be damaged. However in most cases ring magnets are used as components within a device and are therefore protected from physical impacts.

FAQ

What are samarium cobalt magnets used for?
Samarium cobalt ring magnets are frequently used as component parts within devices. They are particularly sought after for applications that will subject the magnet to a humid or corrosive environment.
