Alnico Magnets

Alnico magnets are known as the weakest of the permanent magnets, however, their mechanical strength is one of the strongest, compared to Ferrite and Neodymium magnets. They have excellent temperature stability up to 500 degrees Celsius and can withstand extreme temperature fluctuation. They have very good non-corrosiveness and are available at a reasonable price point due to their low manufacturing cost.

Alnico Magnets are often used in applications requiring low magnetic strength or good temperature resistance. They are also popular among classrooms and learning environments for their weak pull force and ability to accurately demonstrates the north and south poles and are great for visually exposing the magnetic field. Also used in electrical automotive, mechanical, aviation and medical industries, they are most notably used in electric guitar pickups - Fender has been using Alnico Rod magnets to build their electric guitar middle-tone, neck and bridge pickups since the late 1940s!

Alnico magnets properties:

  • Produced by the casting or powder metallurgical techniques
  • Chemical composition: Al-Ni-Fe-Co
  • Very hard and brittle
  • Poor resistance to demagnetization
  • Produce good flux density at a reasonable cost
  • Excellent stability over a wide temperature range

Alnico Cylinder Magnets


Cylinder magnets made from Alnico are used for seals, sensors and coin collection machines and most famously, in guitar pickups.

Alnico Pot Magnets


The Alnico pot magnets have a threaded hole and are suited to general purpose holding applications.

Alnico Shallow Pot Magnets


Shallow pot magnets manufactured in Alnico are mostly used for jigs and fixtures, holding and gripping applications where there are height restrictions.

Alnico Block Magnets


Alnico block magnets, also called bar magnets, are often used in educational facilities from primary school through to post-graduate work in a wide range of experimental applications.

Horseshoe Magnets


Horseshoe Magnets, made of Alnico, are very popular with schools and science departments and are used to demonstrate magnetic fields and properties.
