About Neodymium Magnets

Neodymium Disc magnet are the strongest permanent magnet available. Rare Earth magnets come in many grades and are used in applications where a stronger magnetic field is required in a smaller area.

About Titanium Nitrate (TiN) Coating

  • Hard coating that has a very strong bond to the magnet
  • Resilient to most chemicals and environmentally friendly*
  • Protection from humidity and fluids*
  • Finished color is a metallic gold with a smooth surface
  • Thickness of: 2-3 microns
  • Max working Temp: Approximately 500o C

*Due to the coating process of TiN, hang-points on the magnet can occur which could create weak spots in the coating at the location of these hang-points. If this may affect your application, please contact us for assistance.

About Small Discs Magnets

Our Small Disc Magnets are defined as a tiny neodymium magnet with a diameter between 0.0397" (1.01mm) – 0.250" (6.35mm).  The size of the diameter of a disc magnet has a direct impact on the holding force, pull force, and magnetic field profile.  Small disc magnets are predominately used as sensor magnets, medical device magnets, craft magnets, consumer electronics magnets, and holding applications.

Custom Magnets

60% failure rate for this batch.

I know why you are buying these and you do too. After submerging these in a 1% saline solution to test if the TiN coating is porous or not, I had 6 fail in less than 72 hours. I know the coating is exceptionally difficult to put on such a small magnet but at least you could bring the price down a little to compensate for this. I will buy more but expect high failure rates.
