Bonded Alnico

Isotropy AlNiCo Bonded Magnet

Characteristics:

  • Good temp. Stability (temp. coefficient of Br is about ĘC0.02%/K)
  • Excellent magnetic evenness and stability
  • Strong anti-demagnetization

Application:

  • Due to the characteristics of above mentioned, it is widely used as magnetic driven bearing of power energy measuring instrument
  • High stability magnetic sensor
  • Automatic control surveying instrument
