  Magnet materials  as the latest result of the development of rare earth permanent, magnetic materials are called "Best Magnetic" due to their excellent magnetic properties. The magnetic material is an alloy of neodymium, iron oxide, etc. They are also called a magnet. Magnetic has a very high coercive force.  At the same time, the advantages of high density make permanent magnet materials widely used in modern industry and electronic technology to make the instruments, electroacoustic motors, magnetic separation, and magnetization equipment miniaturized. It is possible to reduce the weight and thickness. The advantages of magnets are high-cost performance and best mechanical performances; the disadvantages are that the Curie temperature point is low, and it is easy to be pulverized. It must be improved adjusting its chemical composition and surface treatment methods. Meet the requirements of practical applications. The third-generation rare earth permanent magnet is the...

What is a neodymium magnet?

图片
  What is a neodymium magnet? Neodymium magnets , also known as neodymium iron boron magnets, are tetragonal crystals composed of neodymium, iron, and boron (Nd2Fe14B). In 1982, Masato Sagawa of Special Metals Corporation discovered neodymium magnets. This magnet's magnetic energy product (BHmax) is greater than that of samarium cobalt. Magnet, its maximum magnetic energy product (BH), is more than 10 times that of a ferrite magnet. It was the most significant magnetic energy product globally at that time. Later, it successfully developed a powder metallurgy process, and General Motors successfully developed a melt spinning process for preparing neodymium magnets. NdFeB has excellent mechanical processing properties, and the working temperature is as high as 200°C. This kind of magnet has stable performance and good cost performance. It is the most commonly used rare earth magnet used in electronic products, such as hard drives, mobile phones, earphones, and battery-powered tools. ...
