The key attributes of Cast Alnico are:
► Cast to a variety of shapes
►Very temperature stable
► Can change magnetic orientation
► High Br and Bhmax characteristics compared to ceramic materials.
The key attributes of Sintered Alnico are:
► Mechanically strongest of the Alnicos
►Close tolerance pressing/typically minimum grinding
Both cast and sintered AlNiCo have low Hc when compared to ceramic or rare earth materials.
Applications of AlNiCo Magnets
General applications for both cast and sintered AlNiCo are:
►Electron tubes, radar, traveling wave tubes
►Separators, holding magnets, coin acceptors, clutches and bearings
►Magnetos, motors, generators, meters, instruments, controls, relays, watt-hour meters
►Communications, receivers, telephones, microphones, bell ringers, musical instruments
►Automotive sensors, loudspeakers, cow magnets, distributors
