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

About Nickel Coating on Magnets
- Most common coating on magnets
- 3 Layers of Coating: nickel-copper-nickel (Ni-Cu-Ni)
- Protection of the magnet from corrosion in ambient air
- Not a protective coating from humidity, water, or salt water
- Light protection of the magnet from chipping
- A decorative finish
- Shiny metallic gray finish
- Thickness: 12-25 microns
- Max working Temp: Approximately 200o C
- Gluing nickel coated magnets onto steel or plastic should be done with glue or epoxies specifically designed for magnets.

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.
Need a custom size? These small neodymium disc magnets can be manufactured with the Direction of Magnetization through the thickness or diameter.
|Max Working Temp||80°C|
