What is a neodymium magnet?
NdFeB is simply a kind of magnet. Unlike the magnets we usually see, it is called "Magnetic King" because of its excellent magnetic properties. NdFeB contains a large amount of rare earth elements neodymium, as well as iron and boron, which are hard and brittle.
Since the surface is easily oxidized and corroded, NdFeB must be surface coated. Its usual coatings are NICUNI/Epoxy/Phosphating/Zn/passivation.
As a 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. It is possible to reduce the size, weight and thickness of equipment such as instruments, electroacoustic motors, and magnetic separation and magnetization.
The advantages of NdFeB are high cost performance and good mechanical properties; the disadvantage is that the working temperature is low, the temperature characteristics are poor, and it is easy to be pulverized and corroded. 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 magnet materials, is called "Magnetic King" due to its excellent magnetic properties. NdFeB magnetic material is an alloy of praseodymium neodymium metal, iron boron and so on. Also called magnet.Recommend magnets: About Eason MagnetsEason Magnets has been involved in R&D, manufacturing and sales of permanent magnets since the 2011.
