What is NdFeB?

Neodymium is simply a kind of magnet. Different from the magnets we usually see, it is called "king of magnetism" because of its excellent magnetic properties. Neodymium contains a lot of rare earth elements neodymium, iron and boron, which are hard and brittle.

Because the surface is easy to be oxidized and corroded, NdFeB must be coated. Surface chemical passivation is one of the best solutions.

As a kind of rare earth permanent magnet material, NdFeB has very high magnetic energy accumulation and coercive force. At the same time, the advantages of high energy density make NdFeB permanent magnet material widely used in modern industry and electronic technology, which makes it possible to miniaturize, lighten and thin equipment such as instruments, electroacoustic motors and magnetic separation magnetization.

The advantages of NdFeB are high cost performance and good mechanical properties; the disadvantages are low working temperature, poor temperature characteristics, and easy to be powdered and corroded. Only by adjusting its chemical composition and adopting surface treatment can it be improved, can it meet the requirements of practical application.

Neodymium iron boron magnetic material, as the latest result of the development of rare earth permanent magnetic materials, is called "magnetic king" because of its excellent magnetic properties. Neodymium iron boron magnetic material is praseodymium neodymium metal, ferroboron and other alloys. Also known as magnetic steel.
