  Characteristics and Processing Technology of NdFeB Rubber Magnet

  NdFeB Rubber Magnetic materials, as the latest results of the development of rare earth permanent magnet materials, because of its excellent magnetic properties and is known as "magnetic king". NdFeB Rubber Magnetic material is neodymium, iron oxide and other alloys. Also known as magnet. NdFeB has a very high energy product and power, while the advantages of high energy density NdFeB permanent magnet materials in modern industrial and electronic technology has been widely used, so that instrumentation, electro-acoustic motor, magnetic magnetization It is possible to miniaturize, reduce, and reduce the size of the apparatus. NdFeB has the advantages of high cost performance and good mechanical properties. The shortcomings are that the Curie temperature is low, the temperature characteristics are poor, and it is easy to corrode the corrosion. It must be improved by adjusting its chemical composition and adopting the surface treatment method , In order to achieve the practical application requirements.

  The third generation of rare earth permanent magnet NdFeB is the most powerful permanent magnet in contemporary magnets, its main raw material is rare earth metal neodymium 29% -32.5% metal element iron 63.95-68.65% non-metallic element boron 1.1-1.2% Dysprosium 0.6-1.2% niobium 0.3-0.5% aluminum 0.3-0.5% copper 0.05-0.15% and other elements.

  NdFeB permanent magnet material is based on the intermetallic compound RE2FE14B based permanent magnet material. The main components of rare earth (Re), iron (Fe), boron (B). (R), aluminum (Al) and other metal parts of the alternative, boron content is small, but the use of rare earth ND in order to obtain different properties can be part of dysprosium (Dy), praseodymium (Pr) and other rare earth metals instead of iron can also be cobalt (Co) But plays an important role in the formation of tetragonal crystalline intermetallic compounds, so that the compound has high saturation magnetization, high uniaxial anisotropy and high Curie temperature.

  Process: Ingredients → Melting Ingot / Scraping → Pulverizing → Pressing → Sintered Tempering → Magnetic Testing → Grinding → Cutting Cutting → Electroplating → Finished Product. Which ingredients are the foundation, sintering tempering is the key.

  NdFeB Rubber Magnets production tools and performance testing tools: a smelting furnace, scrapping furnace, E broken machine, air grinding, pressing machine, vacuum packaging machine, isostatic press, sintering furnace, heat treatment vacuum furnace, magnetic performance test Instrument, gauss meter.

  NdFeB Rubber Magnet machining tools: unintentional grinding, spheronization machine, double-end grinding, flat grinding, slicing machine, double-sided grinding, line cutting, shaped grinding and so on.
