Sumitomo Light Metal Industrial Technology Research l1 1994 study of world non-ferrous metals -29 * developed by the Tb-Dy-Fe polycrystalline material law, carry out information consulting services to users meet their urgent needs, and promote the use of the heart. Also launched a powder, rapid solidification, etc. Preparation Method. The application of magnetostrictive materials has also made great progress. Japan Marine Science and Technology Centre has successfully developed the world's highest level of low frequency sound source (water speakers), it is the fault detection system of marine core audio equipment. 200Hz low frequency sound that can be conveyed 1000kra the distance, the device diameter Ira, weight 410kg, can be battery-powered, electro-acoustic conversion efficiency of 2D%. The Marine acoustic systems rely on accurate fault detection test the sound of time passing in the sea to examine the internal structure of a vast system of ocean. In the actuating element, the developed ultra-precision nano-positioning equipment, which by the magnetostrictive rod, coil (1500 turns), SraCo permanent magnet composition. Heating coil to control the thermal expansion causes magnetostrictive rod, the rod and the coil was inserted between the temperature of water cooling pipe, so that force the water temperature controlled at 4-O. 01 ℃. System displacement efficient than 9O. Also developed a lO ~ 10ml / min of liquid flow control castration, which is expected to precision control valves in the semiconductor,[link widoczny dla zalogowanych], automotive, and other aspects of robot applications. Application of super-magnetostriction materials,[link widoczny dla zalogowanych], is vigorously developing. Non-ferrous Market Information News Information Branch opened \The network is open to all and non-ferrous metal production,[link widoczny dla zalogowanych], consumption, research, design and other management decisions related to staff the unit, sales personnel, providing them with much-needed London Metal Exchange (LME), the New York Mercantile Exchange (COMEX), group of about Metal Exchange (NYMEX), Shanghai Metal Exchange, Shenzhen Stock Exchange non-ferrous metals, non-ferrous metals market south of the Yangtze River Nonferrous Metals Exchange spot market and so too the day's metal prices and authoritative commentary on the market , analysis and forecasting and other information, also based on user needs to provide market statistics, the head of the patient.
