CAST ALNICO

Cast alnico is melted and poured into a mould. Once solidified, the material is rough ground and then heat - treated and cooled, sometimes in a magnetic field.

When treated in the presence of a magnetic field, the magnet is called anisotropic. This orients the material to take on a maximum magnetization and allows a higher gauss level.

Applications - 

  • Sensors

  • Electron tubes 

  • Radar

  • Microphone

 

SINTERED ALNICO

Sintered Alnico is made from a powered mixture of ingredients that are pressed into a die under a tons of pressure, sintered in a hydrogen atmosphere and then cooled either within a magnetic field or without.

 

Applications - 

  • Motors

  • Guitar pickups

  • Loudspeakers

  • Cow magnets
