NdFeB Magnets:

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

Because the surface is easily oxidized and corroded, neodymium iron boron must be surface coated. Surface chemical passivation is one of the good solutions.

As a kind of rare earth permanent magnet material, NdFeB has very high magnetic energy product and coercivity. 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 instruments, electroacoustic motors, magnetic separation and magnetization and other equipment.

NdFeB has the advantages of high cost performance and good mechanical properties; The disadvantage is that the working temperature is low, the temperature characteristic is poor, and it is easy to be powdered and corroded. It must be improved by adjusting its chemical composition and adopting surface treatment methods in order to meet the requirements of practical application.
Neodymium iron boron magnetic materials, as the latest result of the development of rare earth permanent magnetic materials, are called "magneto king" because of their excellent magnetic properties. Neodymium iron boron magnetic materials are alloys of praseodymium neodymium metal, ferroboron, etc. Also known as magnetic steel.
