This product measures 1/2" in diameter and 1/4" in thickness and features a #6 countersink through the thickness of the magnet. It is made of a grade N42 neodymium, iron, and boron magnetic alloy blend. This magnetic blend is patent licensed and made under the ISO 9001 quality control systems. They are plated in a nickel-copper-nickel coating for a shiny corrosion resistant finish. Neodymium ring magnets are perfect for use as magnetic fasteners around the home or for use in commercial applications.

Please note that all neodymium rare earth magnets are fragile and require caution when installing to prevent shattering the magnet, and when handling due to their brittle nature and to avoid injury due to pinching.

  • Material: Sintered NdFeB. Grade N42
  • Gauss Rating: 13,200 Gauss
  • Pulling Force: 13.5 lbs.
  • Pole Orientation: Axially magnetized, the poles are on the flat surfaces.

  • Tolerance: The tolerances of all the dimensions are +/-0.002in with coating.

PLEASE NOTE:             

  • All magnets may chip and shatter, but if used correctly can last a lifetime.

    I purchased these magnets for AN experiment and they are very high quality and very useful. High value and high quality with speedy delivery are very hard to find . . . . Until now. I will be returning to Magnets4Sale for another purchase later this year.
    Thank you
