Pay more attention to the characteristics of magnets and understand the fun of life. High-temperature magnet manufacturers will explain the basic characteristics and extraction processes of magnets.
High-temperature magnet manufacturers explain the new achievements of neodymium iron boron magnetic materials as rare earth permanent magnet materials. They are known as "magnetic steel" because of their excellent magnetic properties.

NdFeB magnetic materials are alloys such as neodymium and iron oxide. It is also called magnetic steel. NdFeB has extremely high magnetic energy and force, and the high energy density of high Ningbo Prime Tech Magnet Co., Ltd makes NdFeB permanent magnetic materials widely used in modern industry and electronic technology.
The neodymium iron boron permanent magnet material of the high temperature magnet manufacturer is an intermetallic compound RE2Fe14B permanent magnet material. The main components are rare earth (RE), iron (Fe), and boron (B). In order to obtain rare earth neodymium with different properties, dysprosium (Dy) can be used praseodymium (Pr) and other rare earth metals, iron can also be replaced by cobalt (CO), aluminum (Al) and other metal parts, a small amount of boron, but for intermetallic compounds The formation of the tetragonal crystal structure plays an important role, so compounds with high saturation magnetization, high uniaxial anisotropy and high Curie temperature.
The third generation rare earth permanent magnet NdFeB is a strong magnet in contemporary magnets. The main raw materials of high temperature magnet manufacturers are rare earth element neodymium, 29%-32.5%, metal, iron, 63.95-68.65%, non-metallic elements, boron 1.1-1.2%, dysprosium, 0.6-1.2%, Nb, 0.3-0.5% , Al, 0.3-0.5%, Cu and 0.05-0.15%.
Process flow: batching, smelting, ingot making / flilting, crushing, pressing, sintering, tempering, magnetic flaw detection, grinding, cutting, cutting, electroplating, finished products. Ingredients are the basis, the key is sintering and tempering.
NdFeB magnet production tools and performance testing tools for high temperature magnet manufacturers: melting furnaces, strip furnaces, crushers, air mills, pressure forming machines, vacuum packaging machines, isostatic presses, sintering furnaces, heat treatment vacuum furnaces, magnetic energy testing Meter and gauss meter.
Neodymium iron boron magnet machine tools of high-temperature magnet manufacturers: centerless grinders, thread rolling machines, double-end surface grinding, surface grinding, slicers, double-sided grinding, wire cutting, Tianjin West Lake High Speed, Taizuan, special-shaped and so on.
