Samarium Cobalt(SmCo) magnets are rare earth permanent magnet which have excellent resistance to oxidation and corrosion, Due to high Curie temperature and stable temperature stability, SmCo arc magnet are used in high temperature permanent magnet (PM) motors, generators,aerospace, automotive, and military applications.
Grades&Types of Rare Earth Samarium Cobalt Arc Magnets:
There are two main types of arc Samarium Cobalt (SmCo) rare earth magnet alloy. The older type, typically denoted as (1-5) having one Samarium atom per 5 Cobalt atoms, and the newer Samarium Cobalt magnet alloy, typically denoted as (2-17), having an atomic ratio of two Samarium atoms to 17 Cobalt atoms.
Various grades of Samarium Cobalt(SmCo) arc magnets are available for industrial and commercial applications. The grade range allow for balancing cost, magnetic performance, and operational temperature resistance.The magnetic energy of SmCo arc magnet range from 16 to 32 MGOe.
