Samarium Cobalt (Rare Earth) Magnets are often used in high-temperature applications needing high magnetic performance and where magnetic stability over a wide range of temperatures is important. Magnosphere can help optimize performance and cost with SmCo magnets in grades from 16 to 32 MGOe and temperatures up to 350°C/662°F. Samarium–Cobalt Magnet is a strong permanent rare earth magnet made of an alloy of samarium, cobalt, Fe, Cu, Pr, and Zr.
Square Samarium Cobalt Magnet
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.

Block Samarium Cobalt Magnet
Many grades of Samarium Cobalt magnets exist to support a variety of industrial applications. The range of SmCo magnet grades typically extends from 16 MGOe to 32 MGOe. This range allows for optimizing cost, performance, and operational temperature resistance.
The older version, typically denoted as (1-5) having one Samarium atom per 5 Cobalt atoms, and the newer Samarium Cobalt magnet alloy, typically denoted as (2-17), having an atomic ratio of two Samarium atoms to 14 – 17 Cobalt atoms. (The 14 – 17 atoms are actually comprised of a mix of transition metals, Cobalt, Copper, and Iron, where Cobalt is the most abundant.)
