China's rare earth permanent magnet production is limited to reduce the prospects

Rare earth permanent magnet material is an alloy of the samarium, neodymium rare earth and transition metal mixed composition, Yong-pressure sintering powder metallurgy method, after magnetizing a magnetic field obtained.

Rare earth permanent magnet materials are now known to one of the highest overall performance permanent magnetic materials, it is more than ninety-century magnetic magnets can be used more than 100 times higher than ferrite, Alnico performance far superior than expensive platinum-cobalt alloy magnetic energy is also twice as high. Due to the use of rare earth permanent magnet materials, permanent magnet devices to not only promote the development of small, improve product performance, and that may produce some special devices, so rare earth permanent magnet materials appeared, immediately aroused great attention of the country, and rapid development.

Analysts believe that with the progress of rare earth permanent magnet material is not only the application of computer, automobile, equipment, instruments, household appliances, petrochemicals, healthcare, technology, aerospace and other industries in a variety of micro-motor, and nuclear magnetic resonance equipment, electrical parts, magnetic separation equipment, magnetic machinery, equipment and other needs to generate a strong magnetic field components in the gap, and the emerging field of wind power, new energy vehicles, frequency appliances, energy-saving elevator, oil pumping and other energy-saving high-end rare earth permanent magnet the growing demand for the material, huge application market space.

Developed countries due to the high cost of production of rare earth permanent magnet materials, and the market prices continued to fall, making the production of these countries unsustainable, so the Western developed countries in Europe and America as represented by magnetics companies have entered the industry to adjust. Currently, the global production base of rare earth permanent magnet industry has shifted to China, China has become a major supplier of the world's rare earth permanent magnet materials.

Prospects Industry Research analysts believe that the current international most magnetic patents had expired, the U.S. patent market will all expire this year, the Chinese production of rare earth permanent magnet materials are becoming less and less constrained. Magnetic until all patent expires, China rare earth permanent magnet materials can not be patented shield free access to international markets and further expand market share, and structural adjustment of export products is also just around the corner.
