AlNiCo Magnets

AlNiCo Magnets are made from aluminum, nickel, and cobalt, with other metals such as titanium or iron as well. These magnets are not as powerful as rare earth magnets, nor are they as inexpensive as ceramic magnets. Alnico alloys have some of the highest Curie temperatures of any magnetic material, around 800 °C although the maximum working temperature is normally limited to around 538 °C. They are the only magnets that have useful magnetism even when heated red-hot. Though they are brittle, they are highly resistant to corrosion, so AlNiCo magnets are typically only coated to enhance their appearance. Alnico magnets are widely used in industrial and consumer applications where strong permanent magnets are needed like electric motors, sensors, loudspeakers, electric guitar pickups, microphones, and more famously in cow magnets.  The Alnico 5 is the most popular alnico grade and it is also the most cost-efficient. The other grades of Alnico magnets can obtain the same energy level as the Alnico 5, but they are not as cost-efficient.
