Alnico Bars

Alnico rods or alnico bars are made of aluminium, nickel and cobalt magnets. Alnico magnets have a low coercive force which limits the applications of this magnet.


Alnico rods are cylindrical magnets which are usually intended for magnetic field measuring instruments due to their high magnetic induction.

The poles are located on the flat surfaces of the alnico rods, in the same way the magnetisation of the magnet is determined during the heat treatment found in the production of the alnico magnet.

Standard sizes:

The standard dimensions we work with when making alnico rods are shown below, in case the dimensions do not match your needs, we can manufacture them in other dimensions.

Size range A (mm) B (mm)
1,2 - 20 7 - 150


Alnico rods have a high resistance to corrosion, so they do not need any coating.

Alnico rods in this format are perfect for use in the production of aerospace sensors and magnetic filters.

Maximum working temperature:

The standard working temperature is 425°C. For higher working temperatures, please contact our sales department.
