Alnico permanent magnet is an alloy composed of metal aluminum, nickel, cobalt, iron and other trace metal elements.
Casting process
The composition of the metal is different, the magnetic properties are also different, and therefore the uses are also different. Alnico permanent magnets have three different production processes: casting, sintering, and bonding. The casting process can be processed into different sizes and shapes, and casting Compared with the process, sintered products are limited to small sizes, and the produced blank products have small dimensional tolerances and good casting machinability. Among permanent magnetic materials, cast AlNiCo permanent magnets have the lowest reversible temperature coefficient, and the working temperature can be as high as Above 500 degrees Celsius.
