Alnico Magnets
Alnico magnets are permanent magnets made from an alloy of aluminium, nickel, and cobalt. While weaker than rare earth magnets, they are highly valued for their excellent temperature stability, corrosion resistance, and durability, making them ideal for high-temperature and industrial applications.
Alnico magnets are popular for specialised uses where stability and reliability are critical. Their mechanical strength is greater than both Ferrite and Rare Earth magnets. They are available in blocks, rods, horseshoe, and cylinders, with applications ranging from education and science experiments to guitar pickups, holding systems, jigs, and fixtures. Their lower strength compared to neodymium makes them safe for classroom demonstrations, while their stability in extreme conditions makes them useful in manufacturing.

FAQ
What is an Alnico magnet?
An Alnico magnet is made from aluminium, nickel and cobalt alloy. They are hard and brittle with poor resistance to demagnetisation but excellent high-temperature stability and corrosion resistance.
Are Alnico magnets used for guitar pickups?
Yes. Alnico rod magnets are widely used in guitar pickups, particularly by Fender since the 1940s, and remain essential for producing classic guitar tones.
