Alnico Magnets were one of the first magnets available on the market. They are the weakest of permanent magnets and have a magnetic field which is easily prone to demagnetisation. Alnico magnets have largely been replaced by stronger magnets such as Neodymium (Rare Earth) in industrial settings. However, they have excellent temperature stability and very good corrosion resistance. Their mechanical strength is greater than both Ferrite and Rare Earth magnets.
Uses for Alnico Magnets:
Alnico Block and Horseshoe Magnets are often used by teachers and education facilities for experiments that demonstrate magnetic fields and properties. Alnico Cylinders are popularly used by guitarists as guitar pickups. If you require Magnets for manufacturing purposes, Alnico Pot Magnets are great for holding applications, jigs and fixtures.
Alnico magnets properties:
Alnico Horseshoe Magnets are very popular with schools and science departments and are used to demonstrate magnetic fields and properties.
Cylinder magnets made from Alnico are used for seals, sensors and coin collection machines and most famously, in guitar pickups.
The Alnico pot magnets have a threaded hole and are suited to general purpose holding applications.
Alnico Shallow Pot Magnets are mostly used for jigs and fixtures, holding and gripping applications where there are height restrictions.
Alnico block magnets, also called bar magnets, are often used in education facilities for a wide range of experimental applications.
