Bonded AlNiCo Magnet
Alnico bonded magnets are those engineering products that are manufactured by using various techniques and various ingredients. They are available in various shapes, sizes and are used for various industrial applications. They are used in laser printer rolls, motor magnets, color monitors etc.
Characteristics:
- Good temp. Stability (temp. coefficient of Br is about C0.02%/K)
- Excellent magnetic evenness and stability
- Strong anti-demagnetization
- These magnets can be molded into variety of shapes
Applications:
- 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
