Alnico Permanent magnet is hard and brittle. Machining or drilling cannot therefore be accomplished by ordinary methods. Holes are usually cored in at the foundry, and magnets are cast close to final size and then finish machined to closer tolerances.
2.Alnico Magnet Manufacturing Methods
Alnico magnets are manufactured through either casting or sintering processes.

3.Alnico Magnet Surface Treatments
The corrosion resistance of Alnico is considered excellent , and no surface treatments are required. However, Alnico magnets are easily plated for cosmetic reasons if required.
