Sintered Alnico

Sintered Alnico magnet ,which are also alumium nickel-cobaltiron alloys, is usually restricted to smaller sizes. it has slightly lower magnetic properties, but better mechanical strength than cast alnico magnet. Sintered Alnico magnet is widely used in all kinds of sensors, meters, controller speedometer and other applications.
