Sintered neodymium iron boron magnets, commonly known as NdFeB magnets, are permanent magnets with high magnetic strength and a wide range of applications.
NdFeB magnets are made by sintering or compacting a powdered mixture of neodymium (Nd), iron (Fe), and boron (B) under high heat and pressure. This manufacturing process allows for the creation of complex shapes and precise dimensions.
The composition of NdFeB magnets typically includes around 30-35% neodymium, 60-65% iron, and small amounts of boron, along with other elements such as dysprosium and praseodymium to enhance their magnetic properties.
These magnets exhibit exceptional magnetic properties, including high magnetic strength, excellent resistance to demagnetization, and a high maximum energy product. NdFeB magnets are known for their strong magnetic fields and are currently the strongest commercially available magnets.
Due to their exceptional performance, NdFeB magnets find applications in a wide range of industries and products. They are used in electric motors, generators, magnetic separators, computer hard drives, magnetic resonance imaging (MRI) machines, magnetic couplings, sensors, and many other devices and systems that require strong magnetic fields.
In summary, sintered neodymium iron boron magnets (NdFeB magnets) are high-performance permanent magnets with a strong magnetic field. They are produced through a sintering process using a mixture of neodymium, iron, boron, and other elements. NdFeB magnets are widely used in various industries for their superior magnetic properties.
