AlNiCo is the earliest permanent magnet material developed. It is an alloy composed of aluminum, nickel, cobalt, iron and other trace metal elements. According to different production processes, it is divided into sintered AlNiCo and cast AlNiCo. The product shapes are mostly round and square. The casting process can be processed into different sizes and shapes; compared with the casting process, sintered products are limited to small sizes, and the produced blanks have better dimensional tolerances than cast products, and their magnetic properties are slightly lower than that of cast products, but they can The workability is better. Among the permanent magnet materials, cast AlNiCo permanent magnets have the lowest reversible temperature coefficient, and the operating temperature can be as high as 600 degrees Celsius. Alnico permanent magnet products are widely used in various instruments and other applications.
