USA: +1 330 486 0001 Singapore: +65 6779 9091 Magnet The NeoDeltaMagnet consists of NdFeB (n eodymium iron boron) , the "strongest" available ma gnet material. The surface is protected against corrosion by a coating of stannous on nickel. The ring magnets have an axial magnetisation. The dimensional tolerance usually amounts to ±0.1 mm.
