Neodymium magnet alloy, also known as NdFeB magnet, is often mistakenly referred to as "rubidium magnet". It is a tetragonal crystal system formed by neodymium, iron and boron (Nd2Fe14B). In 1982, Sumitomo Special Metals' Shin Sagawa discovered neodymium magnets. The magnetic energy accumulation of this magnet is greater than that of samarium cobalt magnet, which is the largest magnetic energy accumulation in the world at that time. Later, Sumitomo Special Metals successfully developed powder metallurgy method, General Motors successfully developed rotary jet smelting method, can prepare NdFeB magnets. These magnets are the most magnetic permanent magnets available today and the most commonly used rare earth magnets. NdFeB magnets are widely used in electronic products such as hard drives, mobile phones, earphones and battery-powered tools.In order to avoid corrosion damage, it is necessary to do protective treatment on the surface of permanent magnet materials, such as electroplating with gold, nickel, zinc, tin, and surface spraying epoxy resin.
NdFeB magnets of neodymium magnet alloy are permanent magnet materials based on intermetallic compound Nd2Fe14B, whose main components are rare earth elements neodymium (Nd), iron (Fe) and boron (B). The third generation of rare earth NdFeB magnets are the most powerful permanent magnets in contemporary magnets. Its main raw material is 29% - 32.5%, neodymium iron 63.95 68.65%, 1.1 1.2% boron, dysprosium, niobium 0.3 0.6-8% - 0.5% copper, aluminum 0.3 0.5%, 0.05 0.15%, and other elements. Neodymium fe-B magnets are divided into sintered neodymium Fe-B magnets and bonded neodymium Fe-B magnets.
