Hengdian gold magnet ---- large magnetic plant manufacturers introduced the kind of motor magnets Alnico magnets used in motors less iron oxide series, because it is relatively low magnetic properties, but some want to heat more than 350 degrees is necessary to use Alnico. Magnet manufacturers are generally concentrated in Zhejiang, Jiangxi, Guangdong, Jiangsu and other places, Dongyang City, Zhejiang Great Magnetic Materials Factory is a ferrite magnet manufacturer series of factory address, the company's products are widely used in speakers, headphones, electrical, works of art , electrical appliances, health care and other areas. Hengdian Dongyang City, Kim Dae-magnetic iron oxide plant ------- Sourcing magnet magnet is not human invention, a natural magnetite, first discovered and use magnets should be Chinese. So 'compass' is one of four great inventions of the Chinese people. As for the composition that is iron, cobalt, nickel, etc. special atomic structure, atoms have a magnetic moment itself. Usually the molecular arrangement of these minerals confusion. Affect each other to not show the magnetic domain magnetic .. But in external force (such as magnetic field) guide molecular orientation tends consistent on showing magnetism. also known as magnetic iron cobalt and nickel is the most common magnetic substance. Ferrite series retailers, large magnetic plant the appearance of fine gold (certification), Fujian ferrite series provided by the large magnetic Hengdian gold plant. Hengdian Dongyang City, Kim Dae-magnetic Factory (www.jjdct.cn) is an industry leader in Jinhua, Zhejiang, electronics, electrical products manufacturing equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . In the Kim Dae-magnetic plant leadership with the staff warmly welcome all inquiries negotiations to create a large magnetic plant gold better future.
