Strong SmCo Block Permanent Magnets

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.

Strong SmCo Block Permanent Magnets

SmCo magnet is a high performance low temperature coefficient permanent magnet made of samarium and cobalt and other rare earth elements. Sm-Co magnets can be operated at higher temperature up to 300 C. Sm-Co materials come in energy products from 16 MGOe up to 33 MGOe. Their high resistance to demagnetizing influences and excellent thermal stability has ensured Sm-Co as the premium choice for the most demanding motor applications.
