Alnico Cylinder Magnets
Cylinder magnets made from Alnico are used for seals, sensors and coin collection machines and most famously, in guitar pickups.
Amplifiers, actuators and motor applications have also used Alnico magnets due to their impressive flux density
Alnico Magnets are the weakest of permanent magnets however they have excellent temperature stability and very good resistance to corrosion. Their mechanical strength is greater than either Neodymium or Ferrite magnets because Alnico magnets are both hard and brittle.

Alnico magnets are made by casting or sintering aluminum, nickel, and cobalt with iron and small amounts of other metals to enhance the magnet grade’s specific properties. Magnetism is very stable in Alnico magnets, even in high-temperature technical applications. They can be formed in fairly complex shapes and produce highly magnetic fields in certain configurations. Alnico magnets are easily de-magnetized and re-magnetized. Alnico magnets can be plated with a variety of metals or given a coating that is usually red. They do not corrode.
