Properties of Alnico magnets

- Jan 10, 2018 -

Alnico permanent magnet is made of aluminum, nickel, cobalt, iron and other trace elements of an alloy.

The composition of the metal is different, the magnetic properties are also different, so the use is different.Alnico permanent magnet has three different production processes: casting, sintering, bonding [1]. Casting process can be processed into different sizes and shapes , Compared with the casting process, the sintered product is limited to small size, the resulting rough product size tolerance small, good machinability casting. In permanent magnetic materials, cast aluminum nickel and cobalt permanent magnet has the lowest reversible temperature coefficient, work Temperature can be as high as 500 degrees Celsius.
