cnNdFeB is simply a kind of magnet. The difference from the magnets we usually see is that it is called the "magnet king" because of its excellent magnetic properties. NdFeB contains a large amount of rare earth element neodymium, as well as iron and boron, and its characteristics are hard and brittle.
Since the surface is easily oxidized and corroded, NdFeB must be surface coated. Surface chemical passivation is one of the good solutions.
As a kind of rare earth permanent magnet material, NdFeB has extremely high magnetic energy product and coercive force. At the same time, the advantages of high energy density make NdFeB permanent magnet materials widely used in modern industry and electronic technology, thus making the instrument The miniaturization, weight reduction and thinning of instruments, electro-acoustic motors, and magnetic separation and magnetization are possible.
The advantages of neodymium iron boron are high cost performance and good mechanical properties; the disadvantages are low operating temperature, poor temperature characteristics, and easy pulverization and corrosion. It must be improved by adjusting its chemical composition and adopting surface treatment methods. Meet the requirements of practical applications.
NdFeB magnetic material, as the latest result of the development of rare earth permanent magnetic materials, is called "magnet king" due to its excellent magnetic properties. NdFeB magnetic materials are alloys of praseodymium, neodymium, boron and iron. Also known as magnet.
