Abstract

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.

Description

technical field

[0001] The invention relates to a soft magnetic alloy powder, in particular to the application and preparation method of the soft magnetic alloy powder. Background technique

[0002] The existing soft magnetic alloy powders are widely used in military and civilian applications due to their small remanence and coercive force, especially the characteristics of easy magnetization and demagnetization, narrow hysteresis loop, and small hysteresis loss and eddy current loss. It is widely used in the electronic power industry. At present, with the emergence of smart devices and new electric vehicles, soft magnetic materials are endowed with more excellent electromagnetic properties in the application fields of signal transmission, filtering, anti-interference, and micro-motors. , For example: higher magnetic permeability, lower power loss, longer service life, lower cost price, etc.

[0003] At present, soft magnetic materials mainly use FeSi, FeNi, FeCo, MPP, FeSi...
