Ι What Are AlNiCo Bar Magnets?
AlNiCo, short for Aluminum-Nickel-Cobalt, is a non-rare earth metallic permanent magnetic material primarily composed of Aluminum (Al), Nickel (Ni), Cobalt (Co), Iron (Fe), and small amounts of other elements such as Titanium (Ti), Niobium (Nb), and Copper (Cu), which help adjust its coercivity. AlNiCo magnets were once the dominant force in the permanent magnet industry until the emergence of rare earth permanent magnets.
AlNiCo bar magnets are one of the simplest shapes of AlNiCo magnets, similar to AlNiCo block magnets but with a more elongated rectangular shape. They are typically measured by their length, width, and thickness, with the length and width generally being greater than the thickness. Nearly all AlNiCo bar magnets are manufactured through the casting process, primarily due to cost factors. These magnets are commonly used in musical instruments and educational purposes.
