高性能釹鐵硼永磁材料

發布時間:2019-04-10        瀏覽次數:35        返回列表
      高性能釹鐵硼永磁材料的主要原材料為稀土, 稀土分為輕稀土和重稀土, 兩種稀土原料 占產品生產成本的比重均在 27%左右.稀土在高性能釹鐵硼永磁材料的生產過程中損耗率 較高,根據產品精細化程度不同,由 10%至 80%不等.由此可見,稀土原料成本及其損耗 率對產品生產成本影響重大. 我國是世界上稀土儲量和產量最大的國家, 歐洲和美國儲量較 小,受稀土資源的影響,目前,美國已無高性能釹鐵硼永磁材料生產基地,而歐洲僅在德國 和芬蘭共有不到 2,000 噸的產能,亞洲已成為高性能釹鐵硼永磁材料的生產中心,2008 年, 90%以上的高性能釹鐵硼永磁材料的供應來源于亞洲。
