Neodymium magnet, also known as NdFeB magnet, is a tetragonal crystal composed of neodymium, iron, and boron (Nd2Fe14B). In 1982, Masayoshi Sagawa of Sumitomo Special Metals discovered neodymium magnets. The magnetic energy product (BHmax) of this kind of magnet is greater than that of the samarium cobalt magnet, and it was the material with the largest magnetic energy product in the world at that time. Later, Sumitomo Special Metals successfully developed the powder metallurgy process, and General Motors successfully developed the melt-spinning process, which can prepare NdFeB magnets. This kind of magnet is a permanent magnet whose magnetism is second only to that of an absolute zero degree holmium magnet, and it is also the most commonly used rare earth magnet. NdFeB magnets are widely used in electronic products, such as hard drives, mobile phones, earphones, and battery-powered tools. Stick NdFeB Magnet is your good choice.
NdFeB Magnet Button is your good choice.I briefly talked to everyone about where magnets can be used around our lives. As a "magnet king", neodymium iron boron magnets have many uses. Today, the neodymium iron boron magnet manufacturer Tongli Magnetic Industry Xiao Chen came Explain for everyone:
Linear Motor NdFeB Magnet is your good choice.Recently I have encountered many customers who are not sure what magnetic grade they want. In fact, these can be roughly calculated. As long as the mass of the neodymium iron boron magnet is calculated, the approximate magnetic force can be inferred. Formula for calculating the mass of rare earth neodymium iron boron magnets.
The application of neodymium iron boron magnets in electrical appliances is very important, just as magnets are used as the main material in motors. Neodymium iron boron magnets are made of a mixture of iron, boron and neodymium. Their resistance and the diversity of production methods make them so common in daily life that we can find them in almost any field.
Recently, some customers have mentioned what the surface treatment of our NdFeB magnets generally need to be electroplated? We come to talk with everyone about the electroplating of magnets.
From October 2,020, the rare earth prices are increased very high, compare to the lowest point in March 2,020, now the price is increased over 1 times, the market price of Nd/Pr metal is typically - 770,000 RMB/ton, as NdFeB magnets is the biggest market for rare earth, so we can find some information from the market, to give some estimation.
