The application and development of rare earth permanent magnet materials

America - The permanent magnet which was made of neodymium rare earth www.neodymium-magnete.com is one kind of new magnetic materials. This kind of Neodymium Magnets was first developed in the 1980s. It has contained the high magnetic characteristics. The most typically and basic common magnet shapes have included the wafer magnets, ring magnets, arc magnets, bar magnets, round magnets and rectangular magnets. The surface of this kind of earth magnets and motor magnets can be coated with a variety of other materials such as nickel, zinc, epoxy, tin, chromium, silver and gold.

So far, the engineer from website www.neodymium-magnete.com which is the best online seller for E&H Magnetics has said that this is the strongest magnetic material for the permanent magnet such as Arc and Segment magnets. Advantages such as abundant raw materials, low prices and excellent magnetic characteristics have made the development of NdFeB become more rapidly and successfully. This new type has already replaced the traditional ferrite, neodymium nickel and cobalt, samarium cobalt and others. On the other hand, the Neodymium Magnets with rare earth has been widely used in many fields such as instrumentation, automotive, petrochemical industry and magnetic health care products.

According to the perspective of the development of rare earth materials, it can be magnets divided into three generations. The first generation is the samarium cobalt rare earth permanent magnetic material which had developed in the United States in 60 years. This is mainly used in the military field. The second generation was developed in the 1970s. However, its application area is very extensive. Third generation rare earth permanent magnet NdFeB magnetic materials has been developed in the 1980s in Japan. However, it has attracted the attention from worldwide. This is because that not only because the price advantage of earth magnets but also the higher magnetic strength.

The using volume of rare earth NdFeB magnets in 1990 around the world is 2500 tons. This number in 1992 is 4000 thousand tons, 7,000 thousand tons in 1997 and 10 million tons in 2000. In 2000, the world demand for neodymium such as Neodymium Magnets is 3,500 tons. China mainland has contained rich rare earth resources and many countries have imported the rare ingredients from China. Japan¡¯s 80 percent of the ingredients has come from China.

From this information, people should know that the new material for Neodymium neodymium magnets Magnets would have much more bright future within the coming years. This kind of new magnet would be the mainstream in the future. If people are willing to order Neodymium Magnets, the website neodymium-magnete.com would be the best choice for them.
