Alnico magnets , composed of primarily aluminum (Al), nickel (Ni), and cobalt (Co), were developed in the 1940's. This class of magnet remains a preferred material because of its excellent temperature stability, high magnetic flux density, and resistance to corrosion.
Alnico magnets are manufactured through a casting or sintering process. The casting process allows for the magnet to be manufactured into intricate and complex shapes. Sintered Alnico is made from a powdered mixture of ingredients that are pressed into a die under tons of pressure. The Sintering process allows for the magnets to be manufactured to tighter tolerances and higher mechanical strength
 
        Cast Alnico 9 Crystal Magnets have comparatively high magnetic properties and single crystal structure,which are widely used in high-tech field geological detection, aerospace and defence technology

Competitive Advantage:

 

1. High Temperature resistance

2. Comparatively high magnetic properties

3. Dimensional Stability

4. Extented temperature and time Stability


Commonly used for various types of

• Demodulator
• 
Oil Detector
• Cymoscope
