Alnico is a type of alloy made primarily from aluminum, nickel, and cobalt, along with iron and other elements. It is known for its strong magnetic properties, making it a popular choice for manufacturing permanent magnets. Alnico magnets can withstand high temperatures and are often used in various applications, including electric motors, microphones, and guitar pickups. The name "Alnico" comes from the first letters of its main components: aluminum, nickel, and cobalt. These magnets can be shaped into different forms, such as rods or discs, and are valued for their durability and performance in both industrial and consumer products.
