cast Alnico magnet - YY Magnetics

Cast alnico magnet can be made into many sizes and complex shapes, which is not possible with other magnetic materials. It has high magnetic flux density, resistance to corrosion and excellent temperature stability, the maximum working temperature is up to 600℃. Cast alnico magnet is widely used in all kinds of sensors and meters, electronics, instruments, medical instruments, teaching, automobile, aviation, martial and other applications.
