Characteristics and processing technology of ndfeb magnet _ ndfeb strong magnet manufacturers
Ndfeb permanent magnet material is the latest achievements in the development of rare earth permanent magnet materials, because of its good magnetic and is known as & other
The king of the magnet & throughout;
Ndfeb magnetic material is neodymium, iron alloy, etc.
Also known as magnetic steel.
Ndfeb permanent magnet materials with high magnetic energy product, straightening force and high energy density is widely used in modern industry and electronic technology, the instrument, acoustic motor and magnetization of the magnetic separation equipment miniaturization, lightweight and laminating become possible.
The present invention has the advantage of cost-effective, good mechanics performance, defect is low Curie temperature point, temperature characteristic is poor, easy pulverization, powder corrosion by adjusting the chemical composition and the surface treatment method, can achieve the requirement of practical application.
The third generation of rare earth permanent magnet ndfeb is strongest in contemporary magnet permanent magnets.
Its main raw material for rare earth metal neodymium - 29%
Iron 63 5%, the metal elements.
Boron 1 65%, nonmetallic elements.
2%, a small amount of dysprosium add 0.
2%, niobium 0.
Aluminum 5%, 0.
0 5% copper.
Dongguan high-end strong magnet element such as 15%.
Iron boron permanent magnetic material is a kind of permanent magnetic material based on RE2FE14B intermetallic compounds.
The main ingredients for rare earth, iron, boron.
In order to obtain the performance of the different with other rare earth metals such as cobalt (
, aluminum (
Replace such as rare earth and iron, can also use cobalt (
, aluminum (
And other metal parts to replace, and the formation of a square crystal structure of intermetallic compounds of the compounds with high saturation magnetization, high uniaxial anisotropy and high Curie temperature plays an important role.
Technological process: ingredients smelting ingot/stripping powder sintering, tempering, magnetic survey, grinding, cutting electroplating products.
The raw material is a foundation, sintering tempering is the key.
Ndfeb magnet blank production tools and performance testing tools: smelting furnace, cast belt furnace, circuit breakers, air grinding, press, vacuum packaging machine, such as static pressure machine, sintering furnace, vacuum heat treatment furnace, magnetic tester, gauss meter.
Dongguan high-end strong magnet ndfeb permanent magnet machine, centerless grinder, round machine, double-headed grinding machine, surface grinding machine, slicing machine, double-sided grinding machine, wire cutting, tianjin high-speed, west lake bench drill, exceptions, grinding, etc.
