What Is NdFeB?
Oct 08, 2018

NdFeB is simply a kind of magnet. Unlike the magnets we usually see, its excellent magnetic properties are called "magnetic kings".


NdFeB contains a large amount of rare earth elements lanthanum, iron and boron, and its properties are hard and brittle. Because the surface is highly susceptible to oxidative corrosion, NdFeB must be surface coated. Surface chemical passivation is one of the good solutions. NdFeB as a kind of rare earth permanent magnet material has a very high magnetic energy product and coercive force, and the high energy density makes the NdFeB permanent magnet material widely used in modern industrial and electronic technology, thus making the instrument It is possible to reduce the size, weight, and thickness of instruments, electroacoustic motors, and magnetic separation magnetization. The advantages of NdFeB are high cost performance and good mechanical properties. The disadvantages are low operating temperature, poor temperature characteristics, and easy chalking. It must be improved by adjusting its chemical composition and surface treatment. Meet the requirements of practical applications.
