Sintered AlNiCo Magnets
Alnico has a low coercive force, and is easily demagnetized if not handled with care. For optimum performance of Alnico 5, the magnetic length should be approximately 5 times the pole diameter or equivalent diameter. For example, a 0.250” diameter magnet should be about 1.250” long
Application field
Sintered Alnico magnet is widely used in all kinds of sensors, meters, controller speedometer and other applications.
