Electro permanent magnet is composed of NdFeB, Alnico, coil, pole and other components. What are the characteristics of NdFeB, which is one of the main raw materials of electric permanent magnet? NdFeB is a kind of magnet, but it is different from the magnets we usually see, because of its excellent magnetic function, it is called "King of Magnet". NdFeB contains a large amount of rare earth elements neodymium, iron and boron, and its characteristics are hard and brittle. Because the surface is easy to be oxidized and corroded, NdFeB has to be coated, such as nickel plating, zinc plating, chemical passivation, etc. As a kind of rare earth permanent magnet material, NdFeB has high magnetic energy product and coercivity, together with the high energy density of magnets, which makes NdFeB permanent magnet material widely used in modern industry and electronic technology, so that the instrumentation, electroacoustic motor, magnetic separation magnetization and other equipment can be used.

NdFeB is a kind of magnet, different from the magnets we usually see, but it is called "King of Magnet" because of its excellent magnetic function. NdFeB contains a large amount of rare earth elements neodymium, iron and boron, and its characteristics are hard and brittle.


Because the surface is easy to be oxidized and corroded, NdFeB has to be coated, such as nickel plating, zinc plating, chemical passivation, etc.


As one of the rare earth permanent magnet materials, NdFeB has a high magnetic energy product and coercivity, and the advantages of high energy density of magnets, which makes NdFeB permanent magnet materials widely used in modern industry and electronic technology, thus making it possible to miniaturize, lighten and thin the equipment such as instruments, electroacoustic motors, magnetic separation and magnetization.


The advantages of NdFeB are high cost performance and outstanding mechanical characteristics; the disadvantages are low working temperature, poor temperature characteristics, and easy to powder corrosion, it is necessary to adjust its chemical composition and adopt external treatment to improve it, in order to meet the requirements of practical use.


NdFeB magnetic material is called "King of Magnetism" because of its excellent magnetic function. NdFeB magnetic material is an alloy of praseodymium metal and boron iron, also known as magnet steel.
