ALNICO Magnets Technical Information

Home Tech ALNICO Magnets Technical Information

Characteristics and applications: Depending on the processing technology, it is divided into two categories: cast aluminum-nickel-cobalt and sintered aluminum-nickel-cobalt.

A. Cast Alnico: It has the advantages of low temperature coefficient, high temperature resistance, moisture resistance, not easy to oxidize, and good work stability. It is mainly used in automotive parts, instruments, acoustics, motors, teaching, aerospace, and military fields.

B. Sintered Alnico: It is produced by powder metallurgy and is suitable for producing products with complex, light, thin, and small shapes. Widely used in instruments, communication, magneto-electric switches, and various sensors.
