Alnico Magnets are the weakest of permanent magnets however they have excellent temperature stability and very good non-corrosiveness. Their mechanical strength is greater than either Neodymium or Ceramic/Ferrite magnets. Alnico magnets are widely used in industrial and consumer applications where moderate strength permanent magnets are needed; examples are electric motors, electric guitar pickups, microphones, sensors, loudspeakers, magnetron tubes, and cow magnets. In many applications they are being superseded by rare-earth magnets.
Alnico Magnets have excellent temperature stability and are very resistant to corrosion. Alnico magnets come in different shapes such as cylinders, blocks, pots, and the popular horseshoe magnet. Horseshoe magnets are the most recognizable Alnico Magnet.
About alnico magnets
Alnico refers to a family of iron alloys which are composed primarily of aluminum (Al), nickel (Ni) and cobalt (Co), hence the name Al-Ni-Co. Alnico magnets have high resistance to loss of magnetism. They are also one of the most stable magnets if they are handled properly. Alnico magnets are electrically conductive, unlike ceramic magnets. Of the more commonly available magnets, only Neodymium magnets and Samarium magnets are stronger but Alnico Magnets can operate at temperatures up to 500°C
