Aluminum-nickel cobalt (AINiCo) is the earliest permanent magnet material developed. It is an alloy composed of aluminum, nickel, cobalt, iron and other trace metal elements.
Features: High coercive force, high Curie temperature.
Shape: round rod, square, ring, horseshoe, disc, etc,.
Applications: electric motors, electric guitar pickups, microphones, sensors, speakers, traveling wave devices, cow magnets, etc.
There are two different production processes for AlNiCo permanent magnets: casting and sintering.
The casting process can produce magnetic materials into different sizes and shapes as customer need. It is widely using in the market. Among permanent magnet materials, casting AlNiCo permanent magnets have the lowest reversible temperature coefficient, and the operating temperature can be as high as 500 degrees Celsius or more.
Compared with the casting process, sintered products are limited to small sizes, and the rough products produced have small dimensional tolerances.
