Isotropy Alnico Bonded Magnet

Characteristics:

  1. Good temp. Stability (temp. coefficient of Br is about ¨C0.02%/K)
  2. Excellent magnetic evenness and stability
  3. Strong anti-demagnetization

Application:

  1. Due to the characteristics of above mentioned. It is widely used as magnetic driven bearing of power energy measuring instrument.
  2. High stability magnetic sensor
  3. Automatic control surveying instrument
