Alnico magnets are made primarily from aluminum, nickel, cobalt, copper, iron and sometimes titanium. Among all the available magnetic materials, they have high magnetic flux density, resistance to corrosion and excellent temperature stability, the maximum working temperature up to 600℃. Cast Alnico can be made into intricate and complex shapes, which is not possible with other magnetic materials.
 

Competitive Advantage:

 

1. High Temperature resistance

2. Comparatively high magnetic properties

3. Dimensional Stability
