Alnico magnets are of different types depending upon the processing
techniques and applications. Alnico's are popular alloys of aluminum,
nickel, cobalt with certain tint of iron. These magnets are powerful
permanent magnets which can be carved into various shapes and sizes and
then used in various applications. Characteristics
The bar alnico has following characteristics:
- Alnico bar magnets have good thermal stability and are very
suitable for high heat applications.
- They have maximum working temperature which vary between 975
degrees to 1020 degrees.
- Since they are hard and brittle, they cannot be subjected to
conventional machining.
- As compared to ceramics they have high residual induction and
energy product.
- If compared to ceramics and rare earth materials they have low coercive force.
Bar alnico's have following applications:
- Food industries
- Chemical industries
- Separators
- Electronic items
- Small consumer appliances
- Sensors
