Alnico Magnets

Alnico describes a family of materials which is derived from a common base composition comprised of aluminum, nickel, cobalt and iron with varying additions of other elements.

By varying the composition it is possible to tailor the magnetic properties to meet the needs of a wide variety of end use applications.

There are two different manufacturing processes for Alnico: Cast Alnico can be made into many sizes and shapes, whereas Sintered Alnico is usually restricted to smaller magnet sizes. Both processes lead themselves to complex geometries and magnet configurations. Standard Sintered Alnico has tighter dimensional tolerances due to its processing. It also has slightly lower reversible temperature. Coefficient magnetism in permanent magnet materials have excellent working temperatures up to 600°C. Alnico products are widely used in all kinds of meters and other applications.
