前言

本文件按照GB/T1.1—2020《標(biāo)準(zhǔn)化工作導(dǎo)則第1部分：標(biāo)準(zhǔn)化文件的結(jié)構(gòu)和起草規(guī)則》的規(guī)

定起草。

本文件代替GB/T21220—2007《軟磁金屬材料》，與GB/T21220—2007相比除結(jié)構(gòu)調(diào)整和編輯

性改動(dòng)外，主要技術(shù)變化如下：

——更改了E1類合金中的銅、釩等元素典型成分范圍（見(jiàn)表2，2007年版的表1）；

——更改了E類合金在某些條件下的振幅磁導(dǎo)率（見(jiàn)表3，2007年版的表2）；

——更改了E類合金在某些條件下的最低磁極化強(qiáng)度規(guī)定值（見(jiàn)表4，2007年版的表3）；

——增加了F類合金在2800A/m條件下最低磁極化強(qiáng)度的規(guī)定（見(jiàn)表4）；

——更改了E類合金的尺寸限制范圍（見(jiàn)表1，2007年版的表5）。

本文件修改采用IEC60404?8?6：2016《磁性材料第8-6部分：?jiǎn)雾?xiàng)材料規(guī)范軟磁金屬材料》。
