Samarium cobalt (SmCo) is a type of rare earth magnet that has the ability to operate in high temperatures and has superior resistance to corrosion.
Similarly to many other rare earth magnets samarium cobalt is brittle and can be chipped and cracked easily making them unsuitable for applications that require repetitive direct impact to the surface of the magnet. These magnets are often best used in applications where the magnet is recessed into a hole or groove to protect the magnet from impact. This high performance, high temperature magnet is typically found in food and industrial manufacturing industries.

Samarium cobalt (SmCo) magnets were one of the first types of rare-earth magnets and have now been commercially available for almost 30 years. While stronger rare earth permanent magnets have been discovered and made commercially available samarium cobalt is still the first choice magnet for adverse or high temperature environments.
