Abstract :
An enumeration and discussion of the physical, thermal, mechanical and magnetic problems of Alnico permanent magnet materials are presented. Some of the milestones in the development of this class of alloys are shown. The physical properties of cast and sintered Alnico permanent magnets are presented, together with the magnetization losses on heating above room temperature, and the magnetization changes on cooling below room temperature
