AlNiCo Magnets

Permanent magnet Alnico is an iron alloy with the addition of aluminum (Al), nickel (Ni), cobalt (Co) and a few other components that enhance magnetism in addition to iron. Alnico alloys have high coactivity and high Curie temperature. Alnico alloys are hard and brittle and cannot be cold worked, so they must be made by casting or sintering.

Alnico magnets are used in electric motors, electric guitar pickups, microphones, sensors, speakers, traveling wave tubes, cow magnets, etc.

How Are AlNico Magnets Made?

According to different production processes, there are Sintered AlNiCo and Cast AlNiCo. Most of the products are round and square in shape. The casting process can be processed and produced into different sizes and shapes; compared with the casting process, the sintered products are limited to small sizes, and the dimensional tolerances of the produced blanks are better than those of the cast products, and the magnetic properties are slightly lower than those of the cast products, but the processability is better. Among the permanent magnet materials, cast Alnico permanent magnets to have the lowest reversible temperature coefficient and can work at temperatures up to 600 degrees Celsius or more. Alnico permanent magnets are widely used in various instrumentation and other applications.

Features of AlNiCo Magnets

The advantages of Alnico magnets are high reminisce (up to 1.35T) and low-temperature coefficient. At a temperature coefficient of -0.02%/°C, the maximum operating temperature can be around 520°C. The disadvantages are very low coactivity (usually less than 160kA/m) and a non-linear demagnetization curve. Therefore, although Alnico magnets are easily magnetized, they are also easily demagnetized.
