Technical Specifications

  • Diameter: 60mm (0.24")
  • Thickness (Length): 30mm (1.18")
  • Weight: 0.77g
  • Grade: Cast Alnico 5 / 5.4MGOe
  • Coating: Nickel - this provides electrical conductivity
  • Maximum Temp: 525°C / 977°F
    • Never allow like poles (south-south or north-north) to come into contact with each other because it will cause the magnet to be partially demagnetised.
    • Cast AlNiCo magnets are brittle; do not allow them drop to a hard surface, they will break, crack, chip or shatter.
    • Do not attempt to flex, they will snap.

All our Alnico magnets are cast, not sintered and are, therefore, magnetically stronger. They come in a range of grades from 2-9. Many uses call for Alcomax 3, Alnico V or Alnico 500 but these are all names for Alnico 5. These magnets are specifically designed for use where electrical conductivity is required as well as magnetism.

These are primarily used as reed switches, and magnets in sensors.  They are available either unmagnetised, magnetised or magnetised and north pole marked.  If you chose to magnetise them yourself, we recommend using two large neodymium magnets such as 25mm x 5mm neodymium disk magnets.
