AlNiCo magnets

AlNiCo magnets

AlNiCo magnets are permanent magnets. They are an alloy of aluminum (Al), nickel (Ni), and cobalt (Co). Their greatest added value is their high-temperature resistance up to 450 °C. They are also resistant to the outdoor environment, especially to corrosion and acids. The properties mentioned above give possibilities for their application. They are weaker than neodymium magnets - they have less magnetic strength but are not as fragile.

Basic advantages of AlNiCo magnets:

  • High maximum working temperature
    Alnico magnets can be used even at 450°C, which is an exceptional feature compared to other permanent magnets.
  • High corrosion resistance
    AlNiCo magnets are corrosion resistant, i.e. no surface treatment is required.
  • Acid resistance
    AlNiCo magnets are acid resistant and thus suitable for applications in demanding environments.
  • Long lifetime
    Ifused properly, AlNiCo magnets have a long lifetime and can last for many years.

Comparison of different types of permanent magnets

A basic comparison of the different types of permanent magnets can be found in the table as follows.
