Ndfeb is still a sunrise industry in rare earth permanent magnet materials

Ndfeb permanent magnet materials because of their excellent magnetic and high cost performance, since the advent of fast becoming the leader of the market of rare earth permanent magnet, its output account for 90% of the world's rare earth permanent magnetic material production, and with the continuous improvement of preparation technology and production technology, its various performance, application fields are also gradually expanded. Therefore, the amount of the nd-nd-ferromagnetic materials should be a symbol of the high and low level of modernization, and the nd-nd-ti-boron permanent-magnet material is still a sunrise industry in the rare-earth materials industry.

The characteristics and advantages of ndfeb

Ndfeb is a kind of metal elements by rare earth metal neodymium, iron, boron nonmetal elements and trace elements added praseodymium, dysprosium, niobium, aluminum, gallium, and copper compounds composed of elements such as rare earth permanent magnet, simple is a kind of magnet, also called magnetic steel. The magnetic property of nd-ti-boron permanent magnet is excellent, cheap and cheap, widely used, and is known as the "magnetic king". It is the most cost-effective magnet material so far.

Ndfeb permanent magnets with large magnetocrystalline anisotropy field, high intensity magnetic pole, the theory of magnetic energy product for 64 mgoe, its magnetic magnetic steel than the 19th century people use magnetic high of more than 100 times higher than ordinary ferrite, aluminum nickel and cobalt 10 times than expensive platinum cobalt alloy magnetic can still twice as high, the coercive force and high energy density, greatly reduces the magnetic component size, promoted the instruments and meters, electronic electrical, computer, mobile phone and other equipment miniaturization, lightweight, thin and efficient, improve the performance of the product, but also promoted some special device; Ndfeb has good mechanical properties and is easy to be machined.

The application of nd-b rare earth permanent magnet material

The emergence of ndfeb permanent-magnet materials has promoted the progress of human civilization and made great contributions to social and economic development. This kind of material can achieve the function of mechanical energy and the electromagnetic energy transformation, with magneto-optic effect, magnetic resonance effect, magnetic effect and magnetic chemical effect, magnetic biological effect, magnetoresistance effect and hall effect of various physical effects, and was made into function of magnetic components are widely used in computer, transportation, communications, aerospace, industrial automation and medical industry, etc.

At present, rare earth permanent magnet motor is the largest application field of ndfe-boron magnets, accounting for 70% of the total application amount of magnets, and its variety, shape and performance are different. The computer is the largest user of permanent magnet motor, which accounts for 40% to 50% of the acoustic coil motor (VCM). Will ndfeb rare earth permanent magnet materials used in the development of all kinds of motor, the permanent magnet excitation, there is no rotor loss and friction, can be made into high efficiency and energy saving, light quality, small size, large torque, smooth drive at low speed, low noise, long life and maintenance-free motor, significantly reduce the quality of the motor, improve the motor performance, coupled with power electronic technology, makes the application of rare earth permanent magnet motor in electromechanical integration of the product, and achieve a variety of USES a new type of rare earth permanent magnet motor has entered a new stage of development.
