AlNiCo magnet up to 500°C

The AlNiCo magnet consists of an aluminium-nickel-cobalt alloy and is composed as follows: 

  • 51% iron alloy 
  • 24% cobalt 
  • 14% nickel 
  • 8% aluminium 
  • 3% copper
It is used primarily for applications at very high temperatures, as it is heat-resistant up to 500°C. An AlNiCo magnet has about four times the holding power of a ferrite magnet and is corrosion-resistant under normal conditions. It can also be ground.

Properties of AlNiCo magnets

These magnets are characterised by their high temperature resistance. They can be used at temperatures between -200°C and +500°C and are insensitive to temperature fluctuations. Our AlNiCo magnets are axially magnetised through the height and have their magnetic poles on the circular outer surfaces.
Unlike neodymium magnets, for example, these high-temperature magnets are not coated. Uncoated neodymium magnets need a coating, for example of nickel or zinc, to protect them against corrosion. These aluminium-nickel-cobalt permanent magnets have excellent corrosion resistance even without a coating. They also have a comparatively high energy product. 

You can find more information and magnetic characteristics in our magnet encyclopaedia under the entry AlNiCo.


Why the rod shape for AlNiCo magnets? 

One disadvantage of these high-temperature magnets is that they are easily demagnetised by external magnetic fields. The rod shape is recommended because this shape provides good demagnetisation resistance for AlNiCo magnets. A length-to-diameter ratio of 4:1 is optimal.
For this reason, we offer our aluminium-nickel-cobalt permanent magnets as standard rod magnets. The sizes offered all have the length-to-diameter ratio of 4 to 1. An example is our article 50505 with a dimension of Ø10x40mm. 

We can also supply other dimensions on request. Please note that AlNiCo magnets are made from casting moulds. Simple shapes can be cut from rods or blocks in small quantities. 


Overview of the advantages of AlNiCo magnets: 

  • Withstand temperatures from -200°C to +450°C without difficulty and have a high remanence. 
  • The material is extremely hard and has a high mechanical strength. AlNiCo magnets can only be processed by grinding with diamond tools. 
  • They have a high energy product. 
  • The high-temperature magnets are extremely corrosion-resistant even without coating.
