磁铁牌号对照表：钕铁硼、钐钴、铁氧体最接近牌号
每行是一个骏材牌号，各列给出各来源中最接近的公开牌号——钕铁硼：MMPA、VACODYM、信越、NEOMAX、NEOREC、Arnold；钐钴：MMPA、VACOMAX、信越、日立、RECOMA；铁氧体：MMPA、C 系列、TDK FB。手上是国外牌号？在该厂商那一列里找（同一牌号可能对应多个骏材档位），找不到就发给我们匹配。
每格为按公开的剩磁 Br 与内禀矫顽力 HcJ、用同一规则算出的最接近牌号，并非官方声明的等效牌号。候选条件：Br 与骏材牌号相差 5% 以内（留 0.1 个百分点舍入余量），HcJ 为骏材保证值的 90%–135%（铁氧体以产品页公布区间为准，落在区间内视为相同）。符合条件者中取综合距离 (ΔBr÷2.5%)² + (ΔHcJ÷15%)² 最小的。Br 以骏材区间中点对比来源的区间中点（信越、NEOMAX、NEOREC、RECOMA），VAC、MMPA、Arnold 钕铁硼、C 系列与 TDK FB 则用其典型/标称值；各厂保证最小值以其规格书为准。每格显示 Br 差、HcJ 差（+ 表示来源牌号高于骏材）及来源公布的 HcJ（kA/m）：除 MMPA 与 C 系列为典型值、TDK FB 为标称值外均为最小值，这几列的差值是典型值与骏材保证值之比，仅供参考。* 表示宽松匹配：Br 相差超过 2.5%，或 HcJ 低于骏材超过 5%、高于超过 15%。HcJ 偏低可能意味着低一个温度等级（如 AH → EH），请核对候选牌号的额定温度；HcJ 偏高通常意味着更高温度等级、成本也更高。「—」表示本表所录该来源牌号中没有符合条件的，不代表该厂商没有这一档。替换前请对比完整规格书，并请我们确认。

- MMPA 牌号格式为 BHmax (MGOe) / HcJ (kOe)；2000 版标准最高只到 50/11。
- Arnold 将 N52 定为 60 °C、AH 定为 220 °C；骏材规格书分别为 80 °C 和 230 °C。
- 钐钴表多数为「—」，是因为骏材 SMG 系列保证 HcJ ≥1990 kA/m，而 VACOMAX 225 AP/TP、RECOMA 24HE/28HE、信越 R28HS/R32HS、日立 H-26SV 等同一 Br 档的保证值为 1500–1750 kA/m，按本表规则不列为对照。约 300 °C 级的应用中它们仍可替代，欢迎询价确认。
- NEOMAX、NEOREC 与日立钐钴数据取自日立金属（现 Proterial）与 TDK 的存档目录，现行产品线可能有变化。C5、C8 是 MMPA Ceramic 5、8 的惯用叫法，C8A、C8B、C9、C10 为经销商叫法。表中没有的牌号，发给我们帮您匹配。
