Alnico Magnet Manufacturing from TyTekBakker
Alnico magnets are made primarily from aluminum, nickel, cobalt. The advantages of alnico magnets are high magnetic flux density, low temperature coefficient of magnetic properties, high mechanical strength, and overall very stable magnets.
There are two different manufacturing processes for alnico: cast alnico and sintered alnico. Cast alnico can be made into intricate and complex shapes. Sintered alnico offers slightly lower magnetic properties but better mechanical characteristics than cast alnico.
Alnico magnets have high magnetic flux density, high resistance to corrosion and excellent temperature stability. Though the corrosion resistance of alnico is excellent and no surface treatments are required, alnico magnets can be plated for aesthetic applications.
Alnico magnets are widely used in industrial and consumer applications where strong permanent magnets are needed and/or high temperatures are present.
