It mainly have two classification according to different production process, The Cast AlNiCo magnet and Sintered AlNiCo magnet.
2. The picture's product is Cast AlNiCo magnet, Cast Alnico magnet can be processed to be intricate and complex shapes to meetcustomer's demand. Some types of Alnico are isotropic, meaning they canbe efficiently magnetized in any direction. Anisotropic magnetsgenerally have a greater magnetic capacity in their preferredorientation than isotropic.
3. Cast Alnico magnets can be processed with many irregular shapes.
4. Only this permanent magnet can make any shape with high magnetic energy according to customers' requirments.
