Wide Application Of NdFeB Magnets In The Auto Motive Industry

Neodymium iron boron magnets are widely used in medical, industrial and all areas of life activities; especially in the automotive industry field they are widely applied.

With the development of economy, the automobile becomes more and more popular, and now there is an annual output of 59000000 cars in the whole world, while the automobile industry is one of the fields where the neodymium iron boron magnets are applied widely. In each car, generally there has 30 parts using neodymium iron boron magnet, while the use of micro motor number can be as high as 70 in some luxury cars, to complete a variety of control action of the cars. According to the current average using number, we can predict the need of motors will increase from eight hundred million to sixteen hundred million, and each car would need 102 grams of neodymium iron boron magnet.

As the development direction of miniaturization, lightweight and high performance, there will be higher request for the neodymium iron boron magnets used in the car, which will speed up the development of neodymium iron boron magnet, especially the bonded NdFeB permanent magnet.
