Isotropy Alnico Bonded Magnet
 Characteristics:
l Good temp. Stability (temp. coefficient of Br is about ¨C0.02%/K)
l Excellent magnetic evenness and stability
l Strong anti-demagnetization
Application:
l Due to the characteristics of above mentioned. It is widely used as magnetic driven bearing of power energy measuring instrument.
l High stability magnetic sensor
l Automatic control surveying instrument
