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.
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
