AlNiCo magnets are made from aluminum, nickel, and cobalt, with other metals such as titanium or iron present as well. These magnets are not as powerful as rare earth magnets, nor are they as inexpensive as ceramic magnets. However, AlNiCo magnets offer specific advantages that make them ideal for a wide range of applications. AlNiCo magnets are extremely stable and reliable in situations where temperatures fluctuate. They can also be cast in complex shapes such as horseshoes. Though they are brittle, they are highly resistant to corrosion, so AlNiCo magnets are typically only coated to enhance their appearance.
AlNiCo magnets are commonly used in generators, voltage meters, guitar pickups, sensors, radar, bearings, coin acceptors and many other applications. These magnets can be demagnetized, but can also be easily re-magnetized. We offer AlNiCo magnets in a variety of sizes, in disc and block shapes. Please contact us if you need custom-cast shapes.
