Ferrite Permanent Magnets Manufacturer China Rare Earth Magnet Limited
Among permanent magnets, ferrite magnet is highly produced and widely applied in many fields with great performance and reasonable price. According to the statistics, the gross output of ferrite is 350,000 tons in 2004, which accounts 51 percent in world total amounts. With the rapid development of science and technology, the requirements to the matching magnetic functional elements, including ferrite parts, of various electronic devices getting higher and higher, namely, it requires increasingly complex shape, small size and precise processing. Thus, compared with the traditional wet-press method, the new technology of dry-press makes the ferrite properties improved and the processing technology simplified greatly.
Among the world, Japanese enterprises have made the best research on ferrite magnetic materials. Specifically, they have studied almost all the recipes and techniques systematically, and applied for patents mostly. As for the dry-press anisotropic ferrite, they have launched five new grades, including FB5D, FB5DH, FB3N, FB3X and FB3G. Furtherly, FB5 series that was introduced in nearly two years pushed performance of dry-press anisotropic ferrite materials up to a new level, which approach the standard of wet-press products basically. Therefore, parts of dry-press ferrites can applied broadly to micro motor, rotor, accessories of computer and so on instead of wet-press ones.
Domestically, there are also some well-known manufacturers have developed advanced technologies and products of high-performance dry-press anisotropic ferrite, like multi-poles ferrite ring magnets and ferrite arc permanent magnets of asynchronous motor. Particularly, the surface magnetic field of multi-poles ring magnets, including 8-poles, 12-poles, 16-poles and 24 poles, can reach to 2000 gauss.
In a word, as there is a bright prospect of high-performance dry-press anisotropic ferrite magnets, the domestic enterprises should improve magnetic properties continuously and perfect processing technology promptly thus to dominate the global market.
