SmCo Countersunk Ring Magnets

Samarium cobalt magnet is mainly formed by the metal samarium, cobalt and some other rare earth elements of the permanent magnet. It has a high magnetic energy product, super low-temperature coefficient, and the operating temperature can up to 300 ℃. At the same time, it has strong corrosion resistance and oxidation resistance. Therefore, SmCo magnetic steel usually does not need to be electroplated and is widely used in motors, meters, sensors, engines, radar, and other high-tech fields.

SmCo Countersunk Ring Magnets

A SmCo ring magnet is a SmCo disc magnet with a concentric hole inside it. A SmCo countersunk magnet is a SmCo ring magnet with one side appearing as a standard ring but the other side has an angled countersink to ideally allow a screw head to fit inside flush, the countersink angle usually being (but not always) 90 degrees. A SmCo counterbore ring magnet is a ring magnet with a cylindrical flat-bottomed hole on one side that enlarges the main concentric hole to take a cap head screw.
