Cast Alnico magnets are permanent magnets composed primarily of aluminum (Al), nickel (Ni), cobalt (Co), iron (Fe), and copper (Cu), renowned for their ​​exceptional temperature stability​​ (up to 550°C), ​​high residual induction​​ (Br: 0.5–1.33 T), and ​​intrinsic corrosion resistance​​.

Sintered Alnico magnets are permanent magnets manufactured through a powder metallurgy process, combining aluminum (Al), nickel (Ni), cobalt (Co), iron (Fe), and copper (Cu). Unlike cast Alnico, sintered variants offer ​​better mechanical strength​​ and ​​tighter dimensional tolerances​​,
