Application of NdFeB Magnets

Application of NdFeB Magnet

1 auto industry

NdFeB automobile industry is one of the areas in more applications. In each vehicle, generally 30 parts of the use of permanent magnet. Reportedly, foreign luxury cars in the number of micro-motor use has been as high as 70 to complete the various control car action. At present, the 55 million vehicles annually by each motor use from the current average of 20, in 2005 to 30, few will predict the electrical needs of the 800 million now to 1.6 billion. With the small car, and high-performance lightweight develop in the direction of the car magnets used in the increasingly high performance requirements, which will accelerate the Nd-Fe-B permanent magnet, especially the Bonded NdFeB Magnets development. If, Bonded NdFeB magnets in a 50% increase in the vehicle, each vehicle would require 102 g, according to the global automotive output 55 million, the bond anisotropy needs about 5600 T Nd-Fe-B magnets.

2 computer industry

With the advent of the information age, has been formed into the home computer craze. According to the United States market survey, in 2000 alone the world of home PC sales will reach 40 million, in 2005 to about 80 million Taiwan. Promote the development of computer-related components supporting the development of hardware, diskettes, CD-ROM drive is the first to use an aspect of NdFeB more each year for the computer drives the Nd-Fe-B magnets T about 4000, accounting for Nd-Fe-B sales 50%. 1999, the global production capacity of HDD 165.7 million, representing 16 percent growth in 1998. Now being large-capacity HDD, and high-speed data transmission, such as space-saving direction.

3 NMR imaging industry

NMR imaging instrument is the application of 80 new technologies and equipment, its internal organization of the human body can be taken different angles of photographs, it can constitute a three-dimensional images to determine the nature and form of disease, to determine the initial tumor helpful. Superconducting magnets with the past, the disadvantage is that the high cost, high running costs. If ferrite magnets do, a need ferrite magnets for NMR 100 T, and if the switch to NdFeB Magnets do, each only 0.5 T, if future demand in the world market 10,000 Taiwan, in 5000 to T magnet.
