Permanent magnet ndfeb abnormity magnet material is based on intermetallic compounds Nd2Fe14B permanent magnetic material. Relative to the casting Al - Ni - Co permanent magnetic material and ferrite permanent magnet, ndfeb magnets with high magnetic energy product and abnormity coercive force, can suck up the equivalent of a weight of 640 times their own weight. The advantages of high energy density makes permanent magnet ndfeb abnormity magnet material in modern industry and the wide application of electronic technology, so that the instruments and meters, electronic motor, magnetization of the magnetic separation equipment miniaturization, lightweight, thin become possible. Material of ndfeb magnet has the advantage of abnormity high cost performance, good mechanical properties, easy to machining; 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.

Ndfeb magnets abnormity process:

Manufacturing process ndfeb profiled magnets made by powder metallurgy process, will contain a certain proportion of raw materials such as: dysprosium, neodymium, iron, cobalt, niobium, praseodymium, such as aluminum, copper, boron iron by medium frequency induction melting furnace smelting alloy ingot, and then broken into 3 ~ 5 microns powder, and forming technology in the field, after forming the green in the vacuum sintering furnace sintering density and tempering time, thus obtained a certain magnetism of permanent magnet blank. Blank after grinding, drilling, slicing machine working procedure etc, processing via the surface again get the ndfeb abnormity magnet products according to user's requirements.
