Expected to "fifteen" during Y30H-1 series of high-end products will be increasing the proportion of about 40% in 2000 to 60% in 2005 over strong magnet production Y30H-2 above series of high-end brand products can reach 10%, the overall the proportion of exports increased to more than 50%. Because of the rich resources of raw materials, cheap labor and huge application market, NdFeB magnets in China's development has many advantages. With the advent of the patent expiry, "15" period to greater development in the affirmative. In addition to the affordable products steadily dominate the market, focusing on the development of high-end products concave magnet material performance to N45, N38H and N32H, production will reach 10,000 tons. China magnet industry in the 21st century with their own advantages, will become the world's magnetic power. Auxiliary braking system is one of the important parts of oil rigs. When drilling the drill string or casing magnet decentralization, with the driller to operate the main brake to adjust the speed of the drill decentralization, meet the requirements of drilling technology. Permanent magnet eddy current brake if the low-speed brake problem solved, the next promotion and widespread applications in deep drilling rig will be. On large lifting device (such as cranes) motor rotating mechanism plus a permanent magnetic field, eddy current induced magnetic moment of the rotation of the motor to limit the speaker magnet, can reach the speed limit, uniform purpose. The rides, the magnetic field generated by the permanent magnet NdFeB rare earth magnet interference signal strong magnet system can not be considered. If the permanent eddy current brake applied to the recreational facilities will achieve good results. In addition, the permanent eddy current brake Bahn and prospects for this type of linear motor linear actuating device is also very optimistic. Speaker magnets, magnetic new Xin Tong (certified), Shandong magnet provided by the Dongguan City, Tong Xin magnetic Limited. Xin Tong, Dongguan City, the new magnetic Limited (www.dgxtxmagnet.com/) is Dongguan, Guangdong, magnetic leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
