Magnetic Products Technology ship these permanent magnets magnetized or non-magnetize according to customers’ requests. Permanent magnets have high coercive force and therefore keep their magnetic field stably under a proper application after they are magnetized.
The diversity of the magnets Sintered NdFeB Rare Earth Neodymium Disc Magnet N35 Ni
The magnetic force is not only restricted to iron-objects . The best known metals except for iron are cobalt and nickel. The qualities are less pronounced and become first with a strong field visible. Magnets can be used in different areas. In our online-shop you will find a large selection of different products which can be used variously.
Sintered NdFeB Magnets are one of the highest performing rare earth permanent magnets. They utilize neodymium (Nd), iron (Fe), and boron (B) as primary ingredients and are susceptible to demagnetization when exposed to elevated temperatures. Neodymium magnets are a state-of-the-art magnetic material developed with excellent magnetic characteristics: extremely strong relative to size, metallic in appearance and found in simple shapes such as rings, blocks and discs. Many grades can withstand high temperatures, but several factors dictate Neodymium magnet performance. NdFeB Magnets are used in sensors, motors, filter automobiles, magnetic holders, loudspeakers, wind generators, medical equipment, etc.
NdFeB Magnets have the following characteristics:
Super strong Br Resident induction.
Excellent demagnetization resistance capability.
Good Price relative to its high magnetic properties.
Coating is needed for Neodymium Magnet
Surface Treatment Method: Zn, NiCuNi, Ni, Ni + Ni, Gold, Silver, Epoxy, Ni + Epoxy, Teflon
