Alnico Magnets

Alnico is the acronym for the alloy that composes this magnet: aluminum (Al), nickel (Ni) and cobalt (Co). Our Alnico magnets also contains iron and are produced by casting or powder metallurgical techniques.

Choose Alnico Magnets for greater mechanical strength, high temperatures and corrosion resistance

Although Alnico might be the weakest of permanent magnets, it presents a greater mechanical strength than Neodymium of Ferrite magnets, and has an excellent temperature coefficient that gives it exceptional stability, even during temperature fluctuations, and make it able to tolerate high temperatures up to 500°C. Another of its properties is its high resistance to corrosion.

Very hard but brittle, our economical Alnico magnets produce an important flux density. However, they are not suitable for high-friction or repelling applications and present a low resistance to demagnetization.

Alnico magnets: A premium cross-field manufacturing material

Alnico magnets are utilized in the mechanical, electrical automotive, aviation, medical industry and in military technology. They are also commonly used for educational purposes given their pole painted colours and pole identification.

More famously, they are first-class material for guitar pickups: Fender has been using Alnico Rod Magnets to build their electric guitar middle-tone, neck and bridge pickups since the late 1940s.

Check our Alnico Magnets in various shapes and sizes: Cylinders, Shallow Pots, Blocks or our Alnico Horseshoe Magnets.

Alnico Cylinders

alt

Alnico Cylinder magnets, also called Rod Magnets, are commonly used for seals and separators, coin collection machines, sensors, relays and security systems, magnetos, motors. Alnico Rod magnets are even used by Fender for their guitar pickups!

Alnico Pots

alt

Alnico Pot Magnets have a short cylindrical shape with a vertically threaded hole in its center. They are suited to general and specific holding applications like objects or tools, fixing, clamping and mounting, and as holding devices for cutting work

Alnico Shallow Pots

alt

Magnetic Shallow Pots are manufactured Alnico magnets with an almost flat cylindrical shape and a vertically threaded hole in its center. They are ideal for gripping and holding purposes where there are high restrictions.

Alnico Blocks

alt

Alnico Block Magnets, also called Square Bar Magnets, present a great stability to temperature fluctuations and a high residual induction. They are mostly used for educational purposes and experimental applications.

Horseshoe Magnets

alt

Horseshoe Magnets made of Alnico are great for traction and lifting applications along with clamping and retrieval purposes. They are also very popular in schools and Science departments for magnetic fields and properties demonstrations.
