SmCo permanent magnet has high magnetic energy product and high cercive force. Its properties are better than
Alnico,ferrite permanent magnet. Its max. energy product is up to 239kJ/m3(30MGOe), which is three times
of that of Alnico8 permanent magnet, eight times of that of ferrite permanent magnet (Y40). Directions of Magnetization:
Applications:
aerospace, defense industry, microwave devices, communications, medical equipment, instruments, wind power,
a variety of magnetic drives, sensors, magnetic processor, high-end motor, etc.
Advantages:
High resistance to demagnetization, High energy product, good temperature stability, high resistance of corrosion
and oxidation
