Sintered Neodymium and Super magnets
Neodymium Iron Boron (NdFeB) is the magnetic material with highest energy density available today. It requires torque, force, and magnetic induction, which means that it can guarantee the best performance. The magnet is obtained from the rare earth inter-metallic (Neodymium) and the transition metal (Iron).
NdFeB was first developed at the beginning of 80’s. Initially, it was used in the computer industry (voice coil motors), to spread later in many different industrial markets such as brushless PM servomotors, linear motors, loudspeakers, sensor systems, sputtering systems (magnetron), magnetic resonance equipment, rotating coupling.
Strong industrial Neodymium magnets are produced by sintering. Unlike ceramic ferrite, the process is performed in the inert gas atmosphere. After that, the magnet can be isostatically pressed in an oil bath or in a die, which gives the product an axial or diametric orientation. Pieces will be then duly processed, grounded, and refined with diamond tools.
High-Quality Industrial Neodymium Magnets
The high energy density allows the production of very high residual flux density (Br), in order that a high performance, as well as high coercive force is enabled, which means high resistance to demagnetization effects. It also has a good temperature behavior, as it can be used at more than 200 °C.
Corrosion resistance is guaranteed by the electrochemical process, Nickel Zinc plating, or by other products such as resin, as well as food compatible materials. Application fields are very diverse including:
- automotive (electric traction, cooling system, setting devices, sensors, loudspeakers)
- house appliance (motors, pumps compressors, sensors)
- railway transportation (electric motors, magnetic levitation)
- military and aerospace
- automation equipment
- electro-medical systems
- food industry (magnetic coupling, moving systems, motors)
- sensors systems
- instrumentation gauge,
- heavy mechanics (lifting systems, magnetic bearing, magnetic levitation)
