Neodymium Disc Magnet Ø3 x 0.5 mm N52 NiCuNi

For small, tight fastenings

You're looking for something that takes up little space but stays firmly in place. This neodymium disc magnet of Ø3 x 0.5 mm feels small in your hand, with its flat round shape and the hard NiCuNi finish that looks smooth and fits neatly against metal.

What you notice about N52

The core is NdFeB with N52 magnetization, so you get a lot of holding power from a very compact size. Handy for displays, sensors, model making, or a magnetic board where you prefer not to see a thick edge. Small. But powerful.

For indoor and careful use

The nickel-copper-nickel coating provides protection against wear and some corrosion, but this is primarily a magnet for dry indoor spaces. Use it carefully with electronics or on workbenches, as it quickly attracts and can pinch if you let it slip.
