一种低成本高矫顽力稀土永磁材料
摘要：
本发明涉及一种低成本高矫顽力稀土永磁材料，包括稀土元素、铁、硼、锌、锰、钛、锡、锆、铬、铝，各组分的重量百分比为：稀土元素20?35％，硼0.8?1.5％，锌0.02?0.2％，锰0.5?5％，钛0.1?3％，锡0.02?0.5％，锆0.02?0.5％，铬0.02?0.5％，铝0.5?5％，余量为铁以及不可避免的杂质。该稀土永磁材料在力学性能和矫顽力方面均得到了较大的改善，并且成本低廉，制造稳定性高、制造方法简单，容易实现大规模工业化生产。
摘要（英）：

The invention relates to a low-cost and high-coercivity rare earth permanent magnetic material which is prepared from the following components in percentage by weight: 20 to 35 percent of a rare earth element, 0.8 to 1.5 percent of boron, 0.02 to 0.2 percent of zinc, 0.5 to 5 percent of manganese, 0.1 to 3 percent of titanium, 0.02 to 0.5 percent of tin, 0.02 to 0.5 percent of zirconium, 0.02 to 0.5 percent of chromium, 0.5 to 5 percent of aluminum, and the balance of iron and unavoidable impurities. The mechanical property and the coercivity of the rare earth permanent magnetic material are greatly improved; furthermore, the rare earth permanent magnetic material is low in cost and high in manufacturing stability; a preparation method of the material is simple, and large-scale industrial production is easy to implement.
