Alnico discs

Alnico magnetic discs are aluminium, nickel and cobalt magnets in a flat circular shape. Alnico discs can have various thicknesses; as the magnet gets thicker, the attraction force increases simultaneously.


Alnico discs are permanent magnets with an extreme temperature tolerance. This type of alnico magnets has an axial magnetisation located on the flat faces of the disc.

Disc-shaped alnico magnets are a type of ferromagnetic material that has a high level of magnetic induction and is usually intended for outdoor use.


Standard mesures:

The dimensions with which we work with alnico discs can be seen below. In case you need a disc of a different size, we can also manufacture them in other dimensions.

Size range A (mm) C (mm)
2,25 26,8
9 27,5


Alnico discs are highly resistant to corrosion, i.e. they have a low tendency to material wear due to chemicals. This is why we supply them uncoated.

Maximum working temperature:  

Alnico discs have a high stability at high temperatures, which is why it has the ability to maintain its magnetic properties at 425°C. As well as the sizes, in the event that a higher temperature is required, we can also manufacture them.
