NdFeB magnet:
NdFeB is the most advanced commercialized permanent magnet material available today.This material has similar properties as the samarium cobalt except that it is more easily oxidized and generally doesn't have the same temperature resistance.
Disc magnet:
The combination neodymium-iron-boron is currently the strongest available magnet material worldwide. Even with small areas, the neodymium disc magnets achieve remarkable holding power, which makes them very versatile. In our shop, you can find tiny, millimetre-flat magnets as well as thick discs with a diameter of several centimetres.
