Ι What Is AlNiCo Horseshoe Magnet?
AlNiCo, an abbreviation for Aluminum-Nickel-Cobalt, is a non-rare earth metallic permanent magnetic material mainly composed of Aluminum (Al), Nickel (Ni), Cobalt (Co), Iron (Fe), and trace elements like Titanium (Ti), Niobium (Nb), and Copper (Cu) to adjust coercivity. AlNiCo magnets were a leading force in the permanent magnet industry until rare earth magnets emerged as a stronger alternative.
An AlNiCo horseshoe magnet, also called a C-shaped or U-shaped magnet, is a distinct type of AlNiCo magnet. Recognized as a universal symbol for permanent magnets and magnetism, an AlNiCo horseshoe magnet is typically produced via casting, the more common method among the two primary manufacturing processes—sintered and cast—each suited for specific applications. Initially, an AlNiCo horseshoe magnet was mainly used for holding applications. Today, it is more frequently utilized in educational settings, demonstrating the principles of magnetism and magnetic fields to students and researchers.
