JLMAG RARE-EARTH CO., LTD (JLMAG) is a leading high-tech enterprise which specializing in NdFeB magnetic material within the complete areas of R&D, production and sales. The company collimates the opportunity of the development in the fields of new energy and energy-saving, has been completed a high-performance magnetic production line of 6000 tons per year with a total investment one billion CNY, and will become one of the greatest professional NdFeB manufacturers with a capacity of 10,000t/year in the second phase.
According to the demand of the high-end application areas, the company has brought in international advanced equipments of production, testing and R&D from Japan, France, etc., established perfect production process and quality management system and got the quality certification of ISO9001:2008; ISO14001:2004; ISO/TS16949：2009. By virtue of a strong production level and manufacturing advantage, the products from JLMAG RARE-EARTH CO., LTD (JLMAG) are widely used in wind power, new energy automobile, inverter air conditioner, IT industry, energy-saving elevator, petrochemical and medical appliance, etc., and established close strategic partnership with international leading enterprises of various industries.
Ganzhou, in Jiangxi province, is the hometown of heavy rare earth throughout the world, which supplies 70% demands of heavy rare earth. The company owns a stable advantage of resource ration through the equity cooperation with the local mining leading industry so that it can provides high cost-effective and high-performance magnets chronically and stably. The company has bulk supplied the series grades sintered NdFeB magnet of N52、50M、48H、45SH、40UH、38EH、30AH. With a complete product range, excellent stability, first-class quality and a high cost-effectiveness, the products sale ahead in the market all the way. The year supply in the wind power industry is over 3000 tons, which has emerged as the world’s largest supplier of the permanent magnet wind power generator magnet.
So, they manufacture in Ganzhou, CHINA, hometown of HRE, 70% global supply, they hold upstream equity, with high Dy concentrate $31.43kg ATM, and what are they doing:
" There are three major ways to accomplish this: new material development; design optimization; and process variation reduction. JLMAG has been able to reduce the content of dysprosium and terbium in magnetic alloys using the process and recipe of raw material formulation optimization."
" This process and formulation optimizations have resulted in many heavy rare earth free magnetic alloys. The development of the newest VH alloys has been a positive side-effect of the heavy rare earth reduction program. The VH grades reach HcJ levels >3,200kA/m at room temperature suitable for applications of typically <250°C."
"Critical review of current and old magnet designs often offers changes for heavy rare earth reduction as well. Overdesign of HcJ leads to overdesign of magnetic alloys. In many cases, a slight reduction of temperature or reduction of HcJ has resulted in a significant decrease of heavy rare earth elements needed in the magnetic alloy." (refer Dr Stan Trout Dysy 2.0)
" This offers good potential to reduce the content of heavy rare earth elements because the nominal value of HcJ can be reduced when the variation is reduced as well (Figure 6). The combination of these efforts to reduce heavy rare earths has resulted in heavy rare earth free N, M and most H grades. Other heavy rare earth free grades are currently under development."
