Magnetic magnets, commonly referred to as the magnetic material refers to a ferromagnetic material is old and uses a very wide range of functional materials Guangzhou Machinery magnets, and magnetic materials as early as 3,000 years ago by people understanding and application, such as the ancient Chinese natural magnet as a compass. Modern magnetic materials has been widely used in our life, such as the permanent magnet material is used as the motor horn, applied to the transformer core material, used as the magnetic-optical disc memory, a computer with a magnetic recording floppy disk and the like. Said bits of information on a large, magnetic materials and information technology, automation, mechatronics, defense, national economic aspects are closely related. The generally accepted that magnetic element is defined by excessive iron, cobalt, nickel and its alloys can be directly or indirectly magnetic substances. After pressing the magnetic magnetization demagnetization difficulty can be divided into soft and hard magnetic material. Easily removed after the magnetization of the magnetic substance called soft magnetic material, not easy to go to a magnetic substance called hard magnetic materials. In general, the soft magnetic remanence smaller mold magnet suppliers, larger hard magnetic remanence. NdFeB magnets are the advantages of cost-effective, with good mechanical properties; The disadvantage is that the low point of the Curie temperature, the temperature characteristics are poor, and easy chalking corrosion, so it must be adjusted to take its chemical composition and surface treatment methods improvements to meet the requirements of practical application. NdFeB rare earth permanent magnet material belongs to the third generation, with a small size, light weight and strong magnetic features, is currently the best price-performance magnets, the magnetic circles known as Magneto. The advantages of high energy density make NdFeB been widely used in modern industrial and electronic technology. In the state of bare magnetic, magnetic reach about 3500 gauss.
