                釹鐵硼磁鐵牌號

                釹鐵硼磁鐵每類產品按最大磁能積大小劃分若干個牌號
                釹鐵硼永磁體牌號有:N35—N52,N35M—N50M,N30H—N48H,N30SH—N45SH,N28UH—N35UH,N28EH—N35EH。
                數字牌號
                牌號示例:048021表示(BH)max為366~398kj/m3,Hcj為800KA/m的燒結釹鐵硼磁鐵材料。
                字符牌號
                燒結釹鐵硼磁鐵材料的牌號由三部分組成,第一部分為主稱,由釹元素的化學符號ND,鐵元素的化學符號FE和硼元素的化學符號B組成,第二部分為線前的數字,是材料最大磁能積(BH)max的標稱值(單位為kj/m3),第三部分為斜線后的數字,磁極化強度矯頑力值(單位為KA/m)的十分之一,數值采用四舍五入取整。
                牌號示例:NdFeb380/80表示(BH)max為366~398kj/m3,Hcj為800KA/MR的燒結釹鐵硼磁鐵材料。
