AlNiCo magnet is a type of permanent magnet composed of aluminum, nickel, cobalt, iron, and other trace elements. It has a high coercive force, making it resistant to demagnetization, and is known for its excellent temperature stability and corrosion resistance. AlNiCo magnets can be made in a variety of shapes and sizes, including bars, discs, and horseshoes, and are used in a range of applications, including electric motors, generators, and sensors. They have a moderate magnetic strength compared to other magnets such as neodymium and samarium cobalt magnets, but they have good resistance to corrosion and high temperatures. AlNiCo magnets are also relatively easy to manufacture and shape, making them a popular choice for custom applications.

1. Alnico is a magnetic material consisting of Al, Ni, Co, and Fe as its main components, and it is called Alnico

    magnet by combining the first letters of each element.

2. There are two manufacturing methods, casting method and sintering method, and they are also classified

    into isotropic and anisotropic.

3. It is used for various purposes such as speakers, microphones, motors, and current meters due to its high

    magnetic flux density and stable temperature characteristics.

4. It can be used stably even at high temperatures of 500-600℃ because of its high Curie temperature, and

    it is also used when magnetic force adjustment is required depending on the application.
