Aluminum nickel cobalt (AlNiCo) is the earliest developed permanent magnet material, which is an alloy composed of aluminum, nickel, cobalt, iron, and other trace metal elements. It has the best magnetic properties and a small temperature coefficient, making it the most widely and widely used in permanent magnet motors.
Sintered NdFeb permanent magnet material has excellent magnetic properties, widely used in electronics, electrical machinery, medical equipment, packaging, aerospace and other fields
Alnico Magnet is composed primarily of Aluminum,Nickel, Cobalt,Copper and Iron. lt have very good corrosion resistance and high max working temperature can reach 550deg.
Neodymium is named as"Magnet King" for its high remanence, high energy. Moreover, it has the high performance and high-cost ration, because of the rich rare earth resources in China and the ever-changing production process and technological progress.
