磁性材料 第1部分:分类

[中文适用范围]： 本标准适用于对大批量生产的磁性材料进行分类。 “磁性材料”表示应用中要求其具有铁磁性或亚铁磁性的物质。 本标准中，磁性材料的分类以公认的主要两类产品为基础： ——软磁材料(矫顽力≤1 000 A／m)； —— 永(硬)磁材料(矫顽力>1 000 A／m)。 在这些土要类别中，当分类合理时可辨别山如下一些特性： ——材料的主要合金元素、冶金状态和物理性能； ——在可能和方便时，可辨认出这些特性间的相互关系。 按特殊应用领域的分类不适用于所有的材料，因为根据其要求的特性，不同的材料常可用于相同的 用途。 [外文原描述]： Intended to classify commercially available magnetic materials. The term "magnetic materials" denotes substances where the application requires the existence of ferromagnetic or ferrimagnetic properties. The classification of magnetic materials is based upon the generally recognized existence of two main groups of products. - soft magnetic materials (coercivity less than or equal to 1000 A/m) - hard magnetic materials (coercivity greater than 1000 A/m) Within these main groups, the classification when appropriate recognizes the following characteristics: - the main allowing element and the metallurgical state and physical properties of the material; - when possible and convenient, the relationship between these characteristics is identified. A classification by specific areas of application cannot be applied to all materials because different materials can very often be used for the same application depending on the characteristics required.
