How powerful magnets are made? Process: formula - - Melting alloy - - Broken - - Flour - - Magnetic field - forming - - Sintering - - - Aging treatment of metal - - - Testing - - - Mechanical processing molding - - - Plating processing. On hybrid and electric vehicles drive motors, Nd - Fe- B( Neodymium - Iron - B) Sintered magnets is indispensable key components. Compared with other magnets, magnet neodymium magnetic force strong, not only can achieve enough to drive the vehicle's power, but also can reduce the size of the to suitable for automotive use of the motor. Of course, in the actual production of high quality ndfeb strong magnet is not so simple. Not only uniform particles for 3 ~ 5 & mu; M size, but also pay attention to the uniformity of shape, but also sintered when heating method, etc. , need to spend a lot of work to create. 'through a substantial accumulation of small technology, reached a practical level it is today' ( The technical personnel engaged in the development of neodymium magnets) 。 Magnet manufacturer to remind you that the magnet device for children has a strong appeal, also bring potential risk of serious damage. The U. S. consumer product safety commission reported in the January 1, 2009 to December 31, 2011 in emergency treatment of 1700 pieces of magnets to devour the events in the magnet device, these 4 - about 1200 involved in the accident Children age 12. Once swallowed, fragments of a powerful magnet to intestinal tract in children together, and clamp body organs, which can lead to intestinal obstruction, organ rupture, pyemia and death. Magnet manufacturer experiment shows: the mobile phone can't simply disappear magnetic reporter first will be a bus IC card flat on the table, after using a mobile phone pin card, with a machine called mobile phone, talking time about 1 minutes 01 seconds. Reporters then this IC card to get the corresponding machine, the results showed that the IC card and no failure. Reporters also use of bank CARDS, smart CARDS and HID card repeat the above 'degaussing test, every phone call control over 1 minute. In using a mobile phone, however, the above three CARDS are 'degaussing after processing, the reporter found that the three CARDS can be in their respective machine normal use, and no demagnetization. Test conclusion: phone calls for a long time, easy to put together the card degaussing, that is not correct.
