Sintered Alnico Magnet
Product Description
Sintered Alnico is manufactured by compacting fine Alnico powder in a press, and then sintering the compacted powder into a solid magnet. It is usually restricted to smaller sizes. It has slightly lower magnetic properties, but tighter dimensional tolerances and better mechanical strength than cast Alnico magnets due to its processing.
Sintered Alnico magnet is widely used in all kinds of sensors, meters, controller speedometer and other applications.
