AINICo permanent magnet is an alloy magnet made from AI, NI, Co, Fe and other trace metal elements and may be produced through either sinteringg or casting process. The product has remarkable resistance against corrosion and high tempperature, and is mainly used in certain precision instruments.
Cast Alnico can be processed to be intricate and complex shapes to meet customer? demand. Some types of Alnico are isotropic, meaning they can be efficiently magnetized in any direction. Anisotropic magnets generally have a greater magnetic capacity in their preferred orientation than isotropic.
Unlike casted Alnico magnets, sintered Alnico magnets offer lower magnetic properties but better mechanical characteristics. Mixes of metal powders are pressed to shape and size, and then sintered at 2300oF in a hydrogen atmosphere. The sintering process is well suited to large volume production, and results in parts that are structurally stronger than cast magnets. Relatively close tolerances can be achieved without grinding.
Characteristic of AlNiCo magnet:
1. High energies and relatively low coercivity.
2. Excellent ability to withstand extreme temperatures stability (as high as 500°C, 930°F)
3. High magnetic flux density, and resistance to demagnetization from vibration and shock.
4. Typical Applications for Alnico Magnets.
Application for AlNiCo magnets:
. Electronic ignition systems . Watt bour meters
. Volt-amp meters . Medical instruments
. Industrial motors . Magnetic reed switches
. Generators Hand tools
. Vending machines
