NdFeB Magnets

Neodymium Iron Boron represents the top of magnetic materials. The exceptional quality of this material is affected by the operating temperature, so it is only possible to use it under certain conditions. Its applications are in a number of different areas and it can be used in special magnetic arrays to achieve remarkable attraction with minimum encumbrance.
