Sintered Sm2Co7 magnets
A Samarium-Cobalt (SmCo) magnet, a type of rare earth magnet, is a strong permanent magnet made of an alloy of Samarium and Cobalt. They were developed in the early 1960s based on work done by Dr. Karl Strnat and Dr. Alden Rey at Wright-Patterson AFB and the University of Dayton, respectively.
SmCo is argueably the best permanent magnet material commercially available, with remanence similar to neodymium magnets, but with higher temperature ratings and with superior temperature stability. There are two types of SmCo magnets, namely SmCo 1:5 and SmCo 2:17.
We can supply SmCo5 magnets of grade 16 to 24 and Sm2Co7 Magnets of Grade 12 to 32.
The (BH)max range of Sm2Co17 is 20 to 32. The max working temperature is 350 degree.
As a result of great brittleness of Sm2Co7 magnets, they're not suitable for complex shapes or thin walled discs or rings. Because of this feature, there may be some appearance defects like small dents.
