High Performance Permanent Magnet Material - NdFeB Magnet

Ⅰ. Introduction to NdFeB Magnet

Neodymium iron boron, also known as neodymium iron boron magnet (NdFeB magnet), is a tetragonal crystal composed of neodymium, iron, and boron (NdFeB). NdFeB belongs to the third generation of rare earth permanent magnet materials. It is currently the most cost-effective and most magnetic permanent magnet. It is known as the "magnet king" in the field of magnetism and is also the most commonly used rare earth magnet material. In the state of bare magnetism, the magnetic force can reach about 3500 Gauss.

Ⅱ. The advantages of neodymium iron boron magnets

NdFeB magnets have extremely high magnetic energy product, coercive force and high energy density. In other words, under the same magnetism, the volume of NdFeB magnets is smaller, which makes NdFeB permanent magnet materials widely used in modern industry and electronic technology, thus making instrumentation, electroacoustic motors, magnetic separation magnetization, etc. The miniaturization, weight reduction and thinning of equipment are possible. The mechanical properties of neodymium iron boron magnets are better than samarium cobalt magnets and alnico magnets, and it is easier to be cut, drilled and processed into complex shapes.

Neodymium iron boron magnets have quite high coercivity, and there will be no demagnetization and magnetic changes under natural environment and general magnetic field conditions. Assuming that the environment is appropriate, even after a long period of use, the loss of the magnetic properties of the magnet will not be large, especially the third-generation rare earth permanent magnet NdFeB is the most powerful permanent magnet in contemporary magnets, with stronger magnetism and attractive force, so it can be applied to any environment without affecting the magnetism and service life of the NdFeB magnet.
