Cast Alnico
|
| Cast Alnico magnets, which are aluminum nickel-cobalt-iron alloys, are the most established and widely used permanent materials, Because of their high flux density and superior temperature stability, cast magnets have been accepted in the widest range of application. Cast Alnico magnets is widely used in speaker, telephone, mobile, odometer, eletricity meter, watermeter, eletricity motor, switch, adhesion and sensors. |
