釹鐵硼強力磁鐵燒結物理特性NdFeB Sintered Magnet Feature

NdFeB強力磁鐵燒結磁石其專利權,目前已由日本住友金屬公司轉售給日立金屬公司,屬于異方性磁石,所以較粘結品磁力較強,其磁能積由N-35~N-52(一般80℃) (BH)max在53MGOe,但也因高溫退磁特性而產生各種不同耐溫牌號(M100℃、H120℃、SH150℃----等等)

輻射取向磁環,以其優良的性能,合理的機構在永磁材料中普遍採用,尤其鐵氧體中使用廣泛。但對於國內燒結釹鐵硼行業來說,充磁方向普遍停留在平行取向水平,輻射取向磁環僅在實驗室試製,還未形成批量供貨能力。
我公司在磁鐵成型工藝上取得光輝業績的同時,公司繼續加強對強力磁鐵產品發展的投入,2003年,本公司科技人員在獨立研製的無等靜壓高度一次成型新工藝基礎上,攻克了輻射取向難題,使國內燒結釹鐵硼強力磁鐵生產工藝取得了突破性提高,並於9月28日申請了發明專利(專利號為00125615.7)。目前,此項技術已達到國際先進水準,此項技術的應用在很大程度上推動了釹鐵硼強力磁鐵應用領域的擴展。
