高磁导率软磁合金粉末、电感件及其制备方法
摘要：
本发明公开的高磁导率软磁合金粉末，合金的组成为Fe-Si-Ni-P-B，其组份如下：Fe＝25.0-80.0质量份，Si＝3.0-8.0质量份，Ni＝15-55质量份，B＝1.0-7.0质量份，P＝1.0-5.0质量份。本发明还公开了采用上述高磁导率软磁合金粉末制成的电感件，以及高磁导率软磁合金粉末的制备方法、电感件的制备方法。采用本发明可制得各种粒度的软磁合金粉末，其磁导率大、功率损耗较低、松装密度较高、振实密度较高、氧含量较低、产品压制性能好、磁环密度高。由于本发明的高磁导率软磁合金粉末其低氧、杂质含量微少、碳含量少、合金成分均匀、球形度好，可作为新型烧结电感的原材料得到广泛应用。
摘要（英）：

The invention discloses high-magnetoconductivity soft magnetic alloy powder. The alloy consists is prepared from the following components in parts by mass: 25.0 to 80.0 parts of Fe, 3.0 to 8.0 parts of Si, 15 to 55 parts of Ni, 1.0 to 7.0 parts of B and 1.0 to 5.0 parts of P. The invention further discloses an inductance piece prepared from the high-magnetoconductivity soft magnetic alloy powder, a preparation method of the high-magnetoconductivity soft magnetic alloy powder and a preparation method of the inductance piece. By the adoption of the preparation method disclosed by the invention, the soft magnetic alloy powder with various particle sizes can be prepared, and the soft magnetic alloy powder is high in magnetoconductivity, lower in power loss, higher in apparent density, high in tap density, lower in oxygen content, high in product pressing performance and high in magnetic ring density. Due to small oxygen content, few impurities, small carbon content, uniform alloy components and high sphericity degree, the high-magnetoconductivity soft magnetic alloy powder can be widely used as a raw material of a novel sintered inductor.
