Samarium cobalt (SmCo), is a member of the lanthanide group on the periodic table. It is a close relative of neodymium. Both of them are called rare-earth elements. They are used to manufacture powerful and permanent magnets. There is a lot of information that a prospective customer should know before buyingsamarium cobalt magnets.
Samarium cobalt magnets are known for the following key properties:
High Magnetic Strength:SmCo magnets have a magnetic energy product (BHmax) ranging from 16 to 32 MGOe, making them the second strongest type of rare earth magnet after neodymium magnets.
Excellent Temperature Stability:These magnets can operate at temperatures up to 300°C or higher, making them ideal for high-temperature applications.
Corrosion Resistance:Unlike neodymium magnets, SmCo magnets are naturally resistant to corrosion and do not require protective coatings.
High Coercivity:SmCo magnets have very high coercivity, meaning they are highly resistant to demagnetization.
Brittleness:SmCo magnets are more brittle than neodymium magnets and can chip or crack if mishandled.
Higher Cost:Due to the inclusion of cobalt, SmCo magnets are more expensive than neodymium magnets.
