  • Alnico magnets are made primarily from aluminium, nickel, cobalt, copper, iron and sometimes titanium. They can be either cast or sintered.   Sintered Alnico Sintered alnico is made from a powdered mixture of ingredients that are pressed into a die under tons of pressure, sintered in a hydrogen atmosphere and then cooled either within a magnetic field or without (anisotropic Vs Isotropic).
    Cast Alnico Cast Alnico melted and poured into a mold. Once solidified, the material is rough ground and then heat-treated and cooled, sometimes in a magnetic field. When treated in the presence of a magnetic field, the magnet is called anisotropic. This orients the material to take on maximum magnetization and allows a higher gauss level. A cast magnet that is not heat-treated in a magnetic field is called Isotropic. After heat treatment and cooling, the material can be ground to specific tolerances and then magnetized. more...

  • Alnico%20Magnets
  • These alnico magnets have excellent temperature stability coupled with high residual induction. High energies characterize alnico magnets that are primarily composed of alloys of aluminum, nickel and cobalt. The alnico magnetss are manufactured through two different processes like casting or sintering. The cast magnets can be manufactured in different complex shapes like horseshoes, which is not possible with other magnet materials. On the other hand sintered alnico offer comparatively lower magnetic properties but better mechanical characteristics than cast alnicos. One of the most commonly used of all cast alnicos is cast alnico 5, which is extensively used for various applications like rotating machinery, meters, instruments, sensing devices, and holding applications, to name a few.

    Machining or drilling cannot be accomplished by ordinary methods as alnico is hard and brittle material. The holes are cored in at the foundry and the magnets are cast close to final size before more...
