The SmCo Magnet is a high performance, low temperature coefficient permanent magnet made of samarium and cobalt and other rare-earth elements. Its biggest advantage is its high working temperature—350℃,It needn’t to be coated because it is difficult to be eroded and oxidized. SmCo magnet is widely used in motors, watch, transducers , instruments, positional detector, generators, radar and other applications.
SmCo Segment finds application in automotive, aerospace, sensors making, and military sectors. It is greatly admired for having compatibility with all types of adverse conditions in terms of temperature and space limitations. This magnetic segment is known to have ability to bear as high as 350 degrees temperature and cryogenic conditions as well. SmCo Segment is made having precise amounts of samarium and cobalt. It has exceptional water resistant properties as it does not get corrode with H2O. arc sintered smco magnets
Features:
Coated with a protective layer of Ni-Cu-Ni
