What is Neodymium Magnets

Apr 15, 2014

The chemical formula which best characterizes the neodymium magnet for Nd FeB, is a kind of artificial permanent magnets. So far, this is the strongest magnetic material, therefore is called the king of the magnet. Feature is found commercialization performance highest magnet ndfeb magnet, magnetic known as the king, with very high magnetic the maximum magnetic energy product (BHmax) is higher than Ferrite (Ferrite), more than 10 times. Its own mechanical processing performance is also very good. Working temperature up to 200 degrees Celsius. And its hard, stable performance, good cost performance, so its application is very extensive. But because of its strong chemical activity, so you must polish layer on its surface. (such as zinc plating, Ni, electrophoresis, passivation, etc.). Production process: the ingredients - system of smelting ingot/sling with - powder - pressed and sintered temper - magnetic detection to grinding to pin cutting processing, electroplating, finished product - from baidu encyclopedia, neodymium magnets (Neodymium magnet) [1], also known as the ndfeb magnet is composed of neodymium, iron, boron (Nd2Fe14B) tetragonal crystal system formed by the crystal. In 1982, sumitomo special metals sagawa reality (Masato Sagawa) found that neodymium magnets. The magnet of the magnetic energy product (BHmax) is greater than the samarium cobalt magnet, is one of the largest material then the magnetic energy product all over the world. [2] later, sumitomo special metals (powder metallurgy process) development success of powder metallurgy method, general motors company development of success (melt - spinning process) rotary spray melting method, to the preparation of ndfeb magnet. [3] this is today's strongest permanent magnet magnetic magnet, also is the most commonly used rare earth magnets (rar neodymium magnets.
