Sintered NdFeB vs Ordinary Ferrite Magnet

Edit:ABM MagneticsDate:2017-09-06 14:07:15【Big middling Small

  Ferrite magnet is a metal oxide with ferromagnetic metal. In terms of electrical properties, the resistivity of ferrite is much larger than that of metal or alloy, and it has high dielectric properties. Ferrite magnetism can also be expressed in high frequency with high permeability. Therefore, ferrite has become a widely used non-metallic magnetic material in the field of high frequency weak current. Non-metallic magnetic materials are composite oxides (or ferric acid salts) of trioxide and other metal oxides. The magnetic force is usually 800-1000 gauss, often used in speakers and speakers.


  The advantages of sintering NdFeB are high cost performance and good mechanical properties. Lack of Curie temperature in low point, temperature characteristic is poor, and is easy to be pulverization corrosion, must through the adjust its chemical composition and take surface treatment methods to improve, to reach the requirements of practical application. The sintered ndb-boron belongs to the third generation of rare earth permanent magnet material, which has the characteristics of small volume, light weight and strong magnetic properties. It is the most excellent magnet in the field, and is known as the magnetic king in the field of magnetic field. The advantages of high energy density have led to a wide application in modern industrial and electronic technology. In the state of naked magnetism, the magnetic force can reach about 3500 gauss.
